Kinda depends on what type of fishing, night shooting from a fan/airboat can result in some fast handling requirements, a rest that contains your arrow , like a whisker biscuit or the newer AMS rest work well.
If you are an " arrow-sighter" you won't like the whisker biscuit though...
For bigger fish and longer shots its nice to have something tunable. F&D makes a nice teflon rest, lots of guys swear by the quickdraw, just depends on what you're doing at the time.
I've got 4 different setups right now, haven't tried the "hydroglide " but it looks good.
