Personally, I will
always prefer real cuero (skin).
However, from 1996-'99 I used X-Ray for the Macho of a pair of first generation Lp "Generation II's" I owned. (which I later sold to a student)
Back in the '90's... the only person (that I knew of) making "pre-made already tucked" X-Ray head's in N.Y.C. was the percussionist 'Emedin Rivera'... who used to attach his own logo/sticker on the top, he called them "EM-RAYS" and sold them through Manny's Music, Sam Ash, Professional Perc., and Drummers World.
I'm am getting ready to mount X-Ray (3 ply) on the Macho of my Lp 1969-'70 Zebras.
I've have had about 15 large X-Ray films since 1997, given to me by some chick I met on the internet, she turned out to be an X-Ray tech. and gave them to me.
I used a dinner plate as a circular form and cut out 3 X-Rays to make a 3 ply head. (see photo)
I went to Cali (J.C.R.) and had him make me four 8' inch long "starter" lugs, which will allow me to easily mount the film, without "starter" lugs you can forget about it, as X-Ray film
can't be put in water like prepping a real cuero.
In the early 1990's, I used to do gigs down in the Manhattan Subway system with four Peruanos who loved to play Cuban Sones y Guarachas (mostly Guarachas).
No tumbadoras... instead they used a Cajon.
I put a few videos of us playing on Youtube, I used the X-Ray on the Macho for the subway gigs because when a group/band gets a permit to play down in the subway, it's for a max. of 3 hours.
The more you play... the more $$$ you make. So the songs would like go for 10-15 min! Imaging your hands at the end of 3 hours. LoL!
But the X-Rays were very loud, tune them once and they stay up.
Believe it or not... we made more money down in the subway then in a club and we had fun, met all kinds of chicks down there!
I'll see how it comes out/sounds on the Zebra Macho, if it's no good... I'll just put the "real deal" on.
I also have a X-Ray on my hand and arm (see photo) that I'd love to use as the playing surface head.

Gigs down in the subway in ''98 or '99, using an X-Ray head on the Macho.
