Hello All. Looking to see who out there has spent time tuning an FI 21 surf wave. Going to be getting one in the next few weeks. Are you using lead? Should I get the transom bag? What are your settings? 60+% of the time its just my son and I while he practices. Also I'll take opinions on some options stinger vs silent stinger? How much quieter is it? Ski pylon? (I dont need it, but will avg buyer want it?) What prop? I'm not at elevation. Only surf, but dont want to be racing the engine to go 20-25mph.
