I can't give you much as to how the Tropical would roll compared to the old-school reactives, but I can tell you that adding surface to the Tropical can and does work wonders (depending upon what you're looking for). I took my Tropical Breeze to 500 grit to get it to read earlier and smooth out the over/under I was seeing at box finish, and the ball was amazing. The grit got it reading the lane sooner and made it SUPER predictable. It allowed me to play up the outside with more confidence than I've ever had since the urethane days. For me, the Tropical Breeze has been one of the best light-oil pieces I've ever thrown, and it became so AFTER I took the surface down to 500.
