I can't remember, but I think it was in 2001 or so when they went to the 460 from the 430. The 460 had the same basic bottom bottom design as the 430 did, but there were a few changes to it. BT came out with their stepped hull in 1997 I believe.....
The 06' and newer BT's have new steps and chines. It really made a big difference. It's the best bottom design BT has ever had.

Just a benchmark here since we are talking about the newer hulls:
2x Merc 700's = Best of 89mph
2x Merc 850's = Best of 95mph
Spiker is building one right now with 1100/1200hp motors, so it'll be cool to see what that runs.

I've hit 75 3 different times in good conditions (cool weather, etc.). Boat planes very well with very little bow rise. This is helped by the newer non-notched transom. The 05 I test drove did take a bit longer to plane and a bit more bow rise. Hit 72 with same motors.
I'm gonna take a hammer and put more pitch in the props so I can keep up with saxman!!!!!
