This was quite detailed and generally captures some of what has been discussed.
More flat water oriented, but I think it translates
Iām a heavy footed surfer and foiler. Not body weight heavy (80kg in winter suit), but I pump and surf like a meathead. I currently prone on an f-one eagle 890 and have a hard time pumping it. I feel like I donāt get enough feedback on my drive down to go weightless and let it rise. Iām thinking about moving to an eagle 990 or sk8 1050. Would the lower aspect sk8 give me more resistance to drive off of than the higher aspect eagle? I know the high aspects are technically āeasierā to pump but I figure style and body type may play a part in what works for each individual
Either the 990 or the 1050 would be fine, but I settled on the 1050. Iāve used them both at 101kg as my grovel wing for very small waves. Its a little easier to get distance with the 990, but the 1050 turns a lot better and I find it a little more forgiving and fun to ride in the surf.
Someone else mentioned the sk8 to be less ādelicateā and I guess like your saying more āforgivableā
Iām pretty heavy footed and have had to learn to be more graceful the hard way. Generally, I think you still want a high aspect for the low drag, it really is a lot more energy to pump the low aspects for distance or time. But just go with a size up on the high aspect until you learn some more finesse. Also I think you want a little more tail which adds a little drag but improves the forgiveness. Possibly a fuselage on the longer side as well.

I have the XS 160 carve monoblock. Gonna see if any 990 eagle or 1050 sk8 pop up for sale and take it from there
I also donāt really run out of energy physically, Iām just inefficient. Bottom line I know itās a skill problem at the core
I was on those wings (Eagle 990 and Sk8 1050) a few months ago, both have a very high stall speed and I think thatās more what youāre dealing with vs. a heavy foot.
If youāre tied to F-One you might want to try the Seven Seas foils, theyāre designed for lower speeds.
Thanks appreciate it! Currently tied to f-one unless I sell it all and start over. Which would be tough
Everyone in my area is tied to F-one as itās most cost effective and thatās what the dealer sells. Problem I see is the SK8 is designed for prone and to be pushed hard by a breaking wave, itās not a super efficient foil. The Eagle is efficient enough for pumping but a bit dead feeling, too pitch stable (and roll stable). Their best wing for pumping is the Eagle X right now.

Looked like an eagle X for the win.
We can now start to put some colour on what professional pumping actually looks like

One thing that has become very clear to me over 5 years of dockfoiling is the the rear tail angle has a huge effect on how much āpowerā and āaccelerationā one can get from a pump. If it feels like your pumps are āweakā and the foil is not giving you much resistance I would recommend changing the tail angle so the leading edge of the tail is angled up more. Angling the leading edge of the tail down makes it easier to pump as the board āautomaticallyā rises back up from the pump, though this makes the pumps less powerful in my opinion. Angling the leading edge of the tail down gives more power to the pump although you have to ācontrolā the pump more by initiating the down and up pump more yourself. You can use shim kits or make your own with washers or stacked thick mailing tape even. When experimenting with tail shims and pumping I suggest going only in 1/4 degree increments and doing 3 or 4 rides or even a whole session at the new 1/4 degree offset and getting used to it and then doing another 1/4 degree. Here is a video of me pumping where I have adjusted the tail shim by 1/8 degree in the end to get it where I like it, so I had to make my own stacked thick mailing tape shim to add on to the Axis shim kit to get it just right. One thing you will see if you can have someone video you is that as you raise the leading edge of the tail your pumping will be so that your feet more and more pump down at the same time. I like to go past the point where I feel really powerful pumps and it get squirrely to ride and then back it off just 1/8 deg or 1/4 deg to where its really good. Note that it is harder to balance and get good takeoffs when the tail is set this way, although it should feel really good when you get a nice takeoff and ride. PS I am riding an Axis 1201 with the 360/45 skinny tail though have modified the 1201 airfoil so cannot give you the āstockā angle that this foil setup corresponds too. I weigh 200 lbs (91kg) here with wetsuit. https://www.youtube.com/shorts/568Bl0VR_nE

Reading that reminds me of bicycle gears.
Easy gear = more shim = less speed, more torque
Hard gear = less shim = more speed but less torque

Wow! Iāve played with angles in 0.5deg increments and never really felt the need to go any more fiddly than that. I guess with flat still water such as we find dockstarting maybe these differences are noticable. For surf foiling and downwinding, a 0.5deg difference is very subtle, 1deg is pretty impactful.
Iām going to start a new topic on this as my new experience on a Code 1250R has shown me how different the handling and design philosophy appears to be between Axis and Code, you will see how this applies to your observation above.
