both PW and AP seem to be excellent Metal drummers, but is that really what we want from a DT drummer? there seemed little variety in the AP videos and just judging PW by the CJS album he seems very same=y and it's all a bit frantic.
That's basically the way I think about PW. He's a great drummer, no question, but there's very little variety in his playing; somehow I get the feeling that his major focus lies on his double-bass playing.
MP's drumming has almost always been about variety (although that element has been receding over the past few years imo), and I think that DT's new drummer should also rely on bringing an interesting groove to the music and not as much on wild, fast, but monotonous playing.
Looking at Marco Minnemann's samples video (and several videos of him playing in a band setting), I think he would be a great choice in that department. That guy definitely knows how to lay a solid groove as a foundation, and that's why I'd be very glad if he became DT's new drummer. Same with Mike Mangini. Thomas Lang plays differently, but he also relies very heavily on the groove and not the frantic playing that can be found so often in nowadays' metal music.
In conclusion, the choice is, of course, up to DT and DT only, but imo, choosing a drummer like PW would be likely to have the consequence of the drumming in DT becoming less interesting and not more.
