Haven't run mine as of yet but for sure a quality looking/feeling spoon - and look very fishy. Just by their weight ( about an onz) they almost feel like a jig so can see why a faster speed and heavier line might be the order. I did however locate some information that seems interesting and a bit contrary to the fast speeds believed needed for this spoon. In fact Matt explains that they will fish well down to Soc speed but above 3 knots they can occassionally spin ( which is not wanted). This could be a bit of good news though for those wanting to run them with other slower fished gear.
Information direct from Matt/ Nog sometime last summer :
" we finally developed one that produces the Right Action anywhere between 2.2 to 3 knots. Beyond 3 knots (ie the idea of running these alongside plugs) works, but in the odd occasion they may spin. There is a remedy to that by relaxing the bends ever so slightly, but I would not suggest doing so unless you are dedicating That spoon to That task. These are TOUGH to modify, and once done, Tough to bring back!
Slower than that, almost right down to dead sockeye slow, the action is exactly what we were seeking.
I have run them occasionally behind flashers, and while that will work (5 - 6 foot lead) that was not my intent from neither a sporting nor commercial application. On the commercial rig, it tends to do best when swum solo, usually above (and behind) a short flasher below. Same is true for sportfishing. Either solo, or IMHO even better just above and behind a dummy flasher, is where it Shines. And a hell of a LOT more FUN fighting just the fish (and not the flasher) in that application."
