Evans lists heads for "Extended Comfort Curve" and for "Comfort Curve". Under the heads listed for Comfort Curve, the Evans site says:
"Fits Classic/Salsa/Valje (tight fit)/Gio Old Models/Original & Patato Fiberglass/Old Galaxy Fiberglass/Matador Models".
So, those listed for the Comfort Curve are the ones you need. You might send Evans an email to verify.
I just installed one of these heads on my tumba and it's too soon to tell if I like it or not. One thing I CAN say--I was counting on the synthetics reducing or eliminating the nasty ringing of my rawhide heads (per the manufacturer's claims). Sorry--not even close. In fact, the overtones are much, much worse than with the natural skins.
What makes it worse is that the overtones appear 'purer'--that is, fewer frequencies with apparently the same amount of energy concentrated in a very narrow band. Extreme sustain, extreme ring, extremely irritated conguero
The only possible positive I can imagine here is that the ringing would be easier to filter out during recording because it is so incredibly clean--the bronze bell of overtones.
Very easy slaps, and the feel is actually very nice. These heads are micro-etched and felt just slightly 'scratchy' at first. But definitely not slippery or greasy feeling.
