I'm a drummer as well! Incredibly cool - when I read your post I was enthralled with memories of when I first started playing; I've been playing for about 9 years now, though I haven't touched a kit in a while - about a year. Coincidentally, it was Rock Band back in 2007 that REALLY skyrocketed my love, passion, and involvement for and with drumming through the roof - and it's an incredible practice tool. Really, really helps you get the syncopation and different styles of rhythm and beats down. Definitely give it a shot if you haven't already.
I have a practice pad that I still practice my rudiments on, however - traditional, marching snare grip usually in the left hand for this, but sometimes I'll switch back over to matched - Traditional grip is *SO* fun - almost impossible to learn, but once you finally crack it it's very, very fun to play with.
Would love to get an actual kit again; I played the actual drum kit in my high school's Steel Drum band - had live concerts in front of hundreds of people and I was rocking the kit leading the group of about 40 melodic steel pan players on stage - including my drum teacher himself.
Probably one of the greatest time's of my life.
This thread is awesome - keep drumming man!
