I've been using Hetman for quite some time now, and I love it. It's at least as fast as Al Cass, but with Al Cass I'd have to re-oil the horn with each playing; with Hetman, I probably oil the valves monthly and every few times I play put a squirt down the leadpipe (under the theory that some of it will work its way to the valve casings, and some will help protect the leadpipe interior from moisture). It also doesn't have the incompatibility issues that Allisyn has. The only downside that I've found is that over the medium-term, it seems to encourage, ummmm... "funky growth". I think specifically because it *doesn't* evaporate quickly, some slimy stuff gets to stay in the casing longer and breed. It's not a major issue, mind you, but it's there.
