I just sold my acoustic set and making the transition to an e-kit. I have done some research over the past week between the Alesis Strike Pro and TD-17KVX, and from the sound of it, the TD is going to last me longer. My main question is the capabilities of this e-kit with expanding to another tom and an extra cymbal or two....or five. Five is a joke of course, but I do want at least one more at some point. I have been reading around and watching videos, but I never seem to get a straight answer. Can some of you guys let me know how much you have been able to expand and update your TD-17KVX? Thanks!
