Try shimming first, it has a huge impact!
A larger stab which is dialed in correctly will have greater top speed potential than a smaller stab (within reason, design dependent). This is because drag due to the creation of lift (induced drag) dominates on a stabiliser toward top speed, moreso than the parasitic drag which is the bulk of the stab moving through the water. Running a larger stab means better inherent pitch stability, less angle required, lower wing loading and less drag.
Add a shim, washer, plastic bread clip, whatever to raise the leading edge of the stab a little and flatten it off.
Personally, I grab my bigger stabs when I'm winging and shim them flat. The opposite for prone foil and downwind.
