Probably your local setup makes it tricky, I have the same issue with local spots and close outs, discussed here.
The thing that caught my attention, your pumping is probably far worse than you realise. If you are getting towed up to speed on the ski on flat water you should be able to pump “very far”. The reason being that you are able to perfectly setup your feet, stay high on the mast, get the cadence right, test pump then let go of the rope. Pumping off the wave you are going very slow, feet wrong, sea is bumpy, you’re out of breath etc etc. Work on your pump.
Lift HA 150 ha x is certainly too high aspect for your surf spot? Can you connect waves on the 170? If not then stick to that. If the surf zone is choppy and aerated water then definitely stick to a medium ~7 aspect foil until you are linking. You need a 4x4 style foil for closeouts, and the 10.1 on your HA X is the opposite.
