The Pro ET shoulc work well with you setup....What pitch are you going with? I assume you're going with a 32P to get you in the low 100's. Keep in mind that with a 32P it's gonna come out of the hull slow and with people in the boat it's even going to be worse...and the acceleration will be below par for that size boat.
Here's an example from my boat...with 32 Merc labbed cleavers I can run 115ish but it pulls like crap and comes on plane slower. With a set of labbed 28P ETs I still run 105ish but it comes on plane quick and is a rocket from 0-105. IMO, with the smaller rocket tunnels it's much more fun to have the hard acceleration/quick plane time rather than a top end number which cannot be run very often because of snotty water.
