Hi DrumBum,
That was a very good deal!!!
As for the heads, The
Remo coated Ambassadors will be fine when you use clears on the reso skins. This is sort of a classic approach.
I had those myself on my kit, I thought they were OK.
I changed over to
Aquarians, which give me a better response for various styles of music.
Personally I like the
Aquarian Texture Coated Heads better than the
Remo's, they are more dynamic/brighter.
I use (as I mentioned before) the Focus-X on my snare, which is a textured coated
Aquarian with a vented clear muffling ring under the edge of the head. This vented muffler took just enough"ring" out of my snare to be balanced.
If you still want abit of a "ring" in an accent-beat just hit it close to the rim and you still get it.
The result is amazing.

I am now totally sold on
Aquarians, you have to play(and feel) the textured coating to realize how good it really is.
For brush-work it is second to none.
Anyway, it is always a very personal thing, I hear a lot of guys swearing by
Evans (G2's for toms), I looked at them and played them in the drum shop and they are certainly not bad.
I am sure that you are now more confused than ever!

One thing is for sure though, those wonderfully crafted Premier shells deserve new heads!!
Cheers and happy Drumming,
Harry
