Yamaha DTXpress/DTXplorer/DTXtreme

Hi there all.

First post but ive been reading for a while.

On a follow up to a previoius post, I am interested in the DtxV2. I 
have a dtxpress one but amd wondering how much better the Dtx is? 

I prefer yamaha kits as I think they have the best jam tracks, which 
is mainly what I use my kit for. However is there any different in 
playabilty over the dtxpress what with the dual zone pads and 
chokeable cymbals...?
