Re: New Ludwig blue sparkle bop kit!
My vote goes for the RIMS mount and L arm with ball mount (from a cymbal stand).
I would keep it a virgin shell, just because they feel/sound better, IMHO. If you're wanting a "boomy" sound, keep it undrilled. If you're ONLY going to use it for a "thuddy" sound, using dampening heads and treating it with pillows or blankets or whatnot, then adding the mount isn't that big of a deal, sound-wise. You would be diminishing the resale value, though, as virgin shells are hot right now. Appearance-wise and functionality-wise, I hear that the DW "banana mounts" are all the rage, if you so choose to go that route (don't do it, don't do it, don't do it...)
