Since we are comparing, I am unsure about a couple of snares. The first, Slingerland GK, or Rogers Dynasonic. I had a slingerland and have been doing research on the Rogers. In you guys wise opinion, which has a better sound. I understand the Rogers is very hard to tune. Thanks Bucky

Dialing in a dyna can be a tricky thing as it has it's own quirks and tweaks.

It took me a while ,but it does sound OK

Personally I think the Fibes SFT 690 is an overall better sounding snare with less tweakiness involved.
