I find thrusters give me more time to gather myself on takeoff. Like they hang around the lip longer and gives me extra time to think if I want to drop in, go left/right, etc...than overall they feel slower but more stable. Twins dont seem to have that hesistation for me. Its like paddling into a wave and the board decides for you. "Oh your definitely going", lol. The Aipa I have is ridiculous on speed. Low rocker, straight rails, wide tail, and no trailer makes it a rocket. It was a bit much at first, but once I figured it out everything else feels slow, especially my hp shortboards.I wonder if this is more of a twin characteristic? I've never had a twin that was quicker out of the gate than a thruster. Could just be the twins I've tried though.
One reason I stopped running a regular thruster set in my Gremlin and switched to a twin+1 was for the get up and go. It was really noticeable when switching the fin sets. I think some like to feel that back fin when groveling to push off of and pump. Thats how I was. Groveling on twins you dont feel that, its more about less pumping and letting the extra glide assist. Took me a while to adjust. Had to slow down my surfing and be less twitchy in a way.
