The hp masts is big leap from the a plus, but if your running a 72 then it should be alright. The longer the mast the more flex they were seeing with wider wings.
The 1125 for small to medium surf is a great wing. Pair with the 180 or 205 tail. It’s an easy wing to use compared to the 925 and has a relatively low stall speed and much lower compared to the 925.
They are a third of the price of the new ha wings as well.
Little update.
A friend (I’d met in a supermarket carpark cos I saw he had a foil in his car) happened to be rigging up when I arrived to go for a prone last Friday.
Was a really fun session on a little right hander.
I managed to pump off a wave and at least got further out than where I’d taken off which was a cool feeling and tried to pump over to another peak and maybe got 50 meters. Little bit of progress.
Was then able to try my friends set up (72, HA925, v tail)
Started out by butchering the first few take offs by just pushing the nose through the water.
Figured that out and then managed a few fun rides.
Holy shit it is so much quicker than my 1550v1. Not that I had a massive go but wasn’t maybe as big a change once actually up an riding in terms of difficulty as I was expecting. Did stall it out by going to slow a couple of times.
Pumping wise the couple attempts I had I felt a bit balanced or didn’t have my feet right so didn’t really feel like I had any good attempts. Even with my wobbliness it felt like I could travel pretty just due to how much quicker it went through the water.
Then when I went back to my 1550 the first wave felt like I was foiling in honey.
Think I’d maybe try pickup a 925 if I found one cheap enough. And just try deal with it being a tricky wing 
.
Anyways. Little ramble of an update
1125 is absolutely amazing winging either the blue or red shim.
Look into KD Maui tails when dropping down to a 925. I have the classic 13" and it allows me to pump for days on the 925.
Yeh would love to give a KD a go and am super keen to give a 1125 a demo if I get the chance. /Would love to demo any of the HA’s on the wingding.
Winged up about 5km from my starting point the other day (in a bay) on a reasonably light day. Was about 15ish knots. And then tried to down wind. A couple 300 metres long rides with wing flagged out was best I managed…
At the very early stages of seeing how it might be even possible to downwind on foil and it’s fuckinnnnn exciting.
Hey everyone
I’m digging up the topic again after some time because I would need your opinion.
I started prone foiling in April, and today I ride almost every day with the Progression 140. I surf the wave, some cut back and shy carve , and I always manage to connect more or less 2 or 3 times before my leg starts burning. I was thinking of keeping my 140 for a while to be comfortable with pumping and continue progressing, connecting more waves… However, everyone is advising and encouraging me to go down in size and use the 125. What do you think?
I am 72kg I think
If your goals are to link waves and build fitness faster keep the 140. If your goals to catch less waves and be slightly more critical go 125p.
I think the 125 and 140 are equally easy to pump but for the 125 you just need to have built up more speed and be good at keeping momentum to get it in that easy to maintain pump range. A guy with a lift 120 usually connects more waves than me on my 140 because he’s better at keeping speed and pumping around on the same waves.
So I would choose more based on steepness and the speed you can get off a wave at your spot.
There’s also a Progression 100 releasing this month so you can run a 140/100 quiver.
Thanks you for your answer. I will go with the 125 tomorrow and let you know how it felt ! 
More speed requires more cardio. Talking with both top tier small riders and heavier pros that ride Uni. There is definitely a pump penalty between the 125 and 140.
It’s just not so black and white. Smaller wings aren’t always “harder to pump” you just need some more help from a wave getting to higher speeds to get it feeling easy. I barely ever use the 125 because of its high stall speed but its not from it being harder to pump its from whether I think the waves will be strong enough to get me fast enough to make it easier
I appreciate your insights and agree that on certain days and conditions, the disadvantages of a smaller wing become less noticeable. I also concur that as wave sizes increase, the need for smaller wings becomes more apparent.
It seems to me that many foilers who aren’t professionals are using wings that are too small for their needs. Ultimately, every record for prone surf pumping has been set using larger wings. The ability to link waves longer is enhanced by wings that facilitate longer pumping times. Flat water pump times generally correlate with the number of waves you can connect (excluding unusual winds, “seams”, and backwash surf locations)
Typical results with high prone skills:
I have been testing this a lot over the past year.
Lol, I was just telling the commenter to try ripping the smaller wing when they’ve got steeper waves and it’ll be fine.
I misread your comment. Looks like you said pump on 125 and 140 was equal. My bad 
I see so many new riders grabbing small wings and getting stuck for years
I also fought with the Takuma V1 fit/construction issues. Finally found a carbon T-bar mast, and took the time to “pot” my 1440 and 1210 wings (as per Mike Pedigo’s video). Now, my joints are super tight, the system is as stiff as the carbon mast allows (I’m only 75kg), and I still like those foils. I also own the Cabrinha H-series wings, hollow mast, etc. Like them too, but the Takuma wings still deliver for me!
The test of the 125 was successful; it was my best session in a long time ! The wing is awesome !
