I'm a bigger guy 190 6'1" that really pushes off my fins. Not sure if it matters but I've heard others say it was over finned with the controllers. For me it was just what I needed to make the baked potato work, pretty sure it would be the same for the sweet potato if you use your fins like I do.
controllers for super wide tail quads. You can try a more upright set for snappier turns, but the compromise is they don't work as well in smaller, weaker waves.
The one experience I had with controllers on a small wave board is the board felt stiff and hard to break out of a line - just too much fin in general. Then again I'm only 155 and usually find myself going for smaller fins unless its big and hollow
I'm about 180 lbs. Controllers felt kinda stiff first day I rode them, but then figured out I needed to shift more weight on the tail during turns (became instinct very quick). I tried switching the fronts out for upright fins and, although the board definitely turned sharper, they'd only excel in pushier waist high waves...performance in the smallest wave range disappeared.
