well since i had both mk1 and mk2, i have to say, that in my feet, the mk1 was not good because it has unnatural rebound. because actually it was like hitting wood.. but then again mk2 with the 2box mesh is also not good.
i have found heaven
get a 2 ply mesh head (i got roland) put it in mk2 and then tell me if it is waaaaay better or not
also id like to reccomend to all to change the snare mesh as well. for me it is vital. i got the drum tech design mesh head and finally i have good rebound. with the 2box mesh i had trouble with paradiddles and stuff, there was way too much bounce and in great speeds it was an obstacle. of course i wont replace the tom mesh , i dont care for them hehe
just my opinion guys
