BTW, just found a T4 in a store 60 miles away. Going over hopefully quite soon to try it out. It's the same store I got my G70 from, so they will let me play it for hours!
I think that the new brush kit IS a lot punchier... strange that everyone that keeps saying they don't want/need/like punchier drums seems to like them when they get them...
Well, that is good news...now you'll be able to hear what I'm raving about...or, if I'm just raving!

It is a deep instrument that will require some quality time, so it is good you have such great access.
I like the punchier drums on the rock stuff...I programmed a nice OrganRockBallad (with Leslie speed change in style)and the "Real Drums" sound pretty impressive and very "live".
But, I don't play a lot of dance/aggressive tunes, so I was happy already with what was being used.
I think a lot of Tyros owners were in that category...the new kits are a nice treat nonetheless.
