The reason why the Surf Adapter is so special is because it enhances everything that made you love your skateboard in the first place. The skateboard deck, trucks, and wheels that you picked out will still feel familiar with the Surf Adapter, and you will still recognize the characteristics that make your skateboard unique.
I've ridden other surf skates, but the Waterborne has a unique ride that for me is the best. Added to existing set-ups - just as described - keeps most of the ride characteristics of the original, but adds a whole other dimension of turn, flow, pump and deep carve. A great innovation!
I tried another brand surfskate truck in the past and really didn't like the rough mechanical feeling of the pumping action. I was skeptical but after seeing they use a urethane bushing in the adapter I gave surfskating a second chance and totally loved it. I just purchased 2 more sets for a few other unloved longboards so they might get more action now. You may not see it on the videos, but using these on really long longboards is crazy fun. I'm using them on a 4 foot long board and plan to try it on an 8 foot longboard soon.
It's pretty awesome, I can stay on my board when going through really tight turns now. I'd suggest getting the rear ones too, it completes the package and the board feels much more stable during high speed (at least for my experience).
