I've used the Revivex quite a bit. I find I'm able to treat my stuff a good 20+ times per 5 oz. bottle. Pretty economical in my experience. Improves breathability too.
right on bushwackers. It's great to see a club thinking about hiring experienced guides. Not that there aren't experienced climbers in the clubs too. I was climbing with someone last weekend who had hired Jason and thought he was great.
