Yamaha DTXpress/DTXplorer/DTXtreme

... I have just bought a Yamaha DTXpressIII standard drum kit. It's my 
first electronic kit (up till now I was just "acoustic") and I must say 
that I like it a lot. 

I am just starting to tweak and play with the samples from the module 
and everything, and I was wondering if you could help me with 
suggestions of using some other samples. (For example what other 
samples do you use? etc.) 

Thanks, guys.

P.S. OldGuyDrummer, I was just looking at the pictures posted on the 
group. Great kit you have there.
