I've tried quite few and usually just stick with owner cutting points and/or gamy octopus style hooks for convenience and because I typically have quite a pile of them on hand.
I have been getting to know the gamy finesse wide gaps in a number of applications lately and I continue to like them. I've rigged a few up as stinger/hang back's on flies and they definitely seem more sticky. The shank doesn't have as dramatic a bend as the octopus, which has great holding power, but not the best hooking angle when hanging down.
The wider gap gets the point a little more out there and the finer wire (as compared to an octopus of the same size) helps with the sticky factor as well. A lighter hook overall and straighter shank help the FWG's ride very well behind a fly. Lots more testing to do but primarily good things to say about them across the spectrum of uses so far.
I've used sickles for stingers as well and don't notice any real differences over the octopus. I like the Mosquitos short, fat profile for beads, but the FWG's are better.
