The 98s are great, I've been using them live for maybe 10 years. We originally had one on the snare as well, and went back to a 57. FYI we use the 91 in the kick, and it's also great.
Bermuda
52 build in kick (combined with SubKick)
56 on gong drum (combined with SubKick build-in)
57 for snare top
57 build-in for snare bottom
98 on toms and aux snares
91 on OH's, ride and HH's
This is my fav. set-up.
I'll be looking at getting an SM81 for the hats at some point...
