I used old Bohning Textite for years and years. Broke with tradition a few years ago and started using ProRelease Black Lightning. It's slick stuff, not tacky like Textite, because it's silicone and graphite based. It seems to dry out pretty fast, but I wax my string and cables at least once a week anyway, so it's no big deal.

When I use a release, I also use it to wax my string loop and it's the cat's arse for that. Keeps the loop stiff for easy hookup butit doesn't build up on my release jaws like Textite did.
