May depend on the drum and your tastes.. I was only able to use the Fiberskyn Diplomats on a Sonor Jungle Kit I had as the reso's. All other drums, I disliked them as reso's.
If you are going to use them as batters and can deal with the known bubbling issue, then they can produce an OK sound assuming it's the sound you like. I've used the FA's a few times as batters with success on various drums all in standard bop kit sizes.
Jeff Hamilton uses them with great success.
Aquarian modern vintage on everything!!
Personal tastes I know but I've tried the Medium and Thin version of these and I didn't care for them. Played them "in" for a few months before I decided to swap them out.
It's all a matter of personal preference though and I know
many that wouldn't trade them for anything.
