Huge help man - thanks. So I’ll go with the heavy coated ambassador top and hazy bottom and try the oil. I didn’t understand your comment about the snare “cord over straps”. The snare wires I have are these:Yeah, that's the original batter head, and after five years I'd think it's had a good long life. Five years is a good long time for a bottom head to last, too, so I'd go ahead and change both of them. Get a bottle of 3-In-One oil for like five bucks and lube up every moving part on the drum, too; especially the snare throwoff. People complain about P-85s, but really all they need is some oil every decade or so. I'm also partial to snare cord over straps; it's a little more flexible, so you can have the snares tighter, but they don't choke the bottom head so much. Those three changes and some good tuning will make your Supra as good as any.
And if you don’t mind giving your opinion on the rest of the heads I’m thinking of going with (with my type of music in mind):
- Rack & floor Tom’s: Clear Evans G2’s for tops and G1’s for bottoms
- Bass drum: Clear Evans EMAD2
