Yeah. I have never been into them personally. Thats not to say they are bad.
I have heard people play them in jazz situations on tom batters tuned up higher and liked them a lot, and I think they look/sound cool as a bass drum reso head on real old drums that might have had calf on them originally, or new drums made in that 1930's-50's style, and especially on 18 inch bass drums, but I have never liked them in a rock setting on any front. Just dont have any character when you bash on em.
I really think it is worth trying 1 ply clear reso heads with a 2 ply coated head on the batter side of the toms. Thats the combo that my 70's Ludwigs sound the best with (to my ear). Try a coated ambassador on the front of the bass drum with a felt strip and a coated emad on the batter side with the drum wide open. I am telling you....its great if you wanna rock!
Hope this helps!
