I'd say it's all in the quality of the piece, they've been around a while, like the others you mentioned, they do things a bit differently, which may or may not mean that you can get help at the track for tuning, myself, I'd probably try to find one of the others, just because they are more common, but that may be an illusion, maybe where you'll be running, some of the guys run them, which would be your next step, ck out who runs what locally, that's where you'll be looking for help, you might find out almost everyone runs them.
