Hey, I currently own a PDP maple kit, it is not the X7 but other than the small 8inch tom, the drum sizes are the same as the X7. I had to change all the factory heads to Evans
g2's on the toms and an eq3 on the bass drum, also replaced the front head on the bass as the factory one was crap. NOW the drums sound like they cost FAR more than I paid for them, including the head changes. That said, Mapex
has a very strong reputation and I'm currently looking at a Mapex
birch kit as my 2nd kit. Mapex
hardware is FAR better than PDP's as well. Hope this helps.
