Charlie Christian is awesome. I like some of Wes, not all though. I'll look into the others. I tend to like other jazz musicians than guitarists. I love Monk, Mingus, Coltrane, Horace Silver, Hawkins, Young.
I like the Jazz Messengers a lot. Django is good. I generally don't care for modern jazz guitarists. Their solos sound like finger exercises and such. I like chord melody a lot. I think in general I like "jazz" not jazz guitarists.
Basically you can achieve the same result with cordovan cream, or reno and a spoon.It is largely bullshit. It is a throwback to "St. Hughes Bones". Many old school shoemakers made their tools out of animal bones so some company decided to profit from that by selling oiled deer bones. Anything hard and smooth can do the same thing. It just compacts the fibers, that's it.
