Stingers fly terrific for me. Woodsman fly terrific too.
But, I've gone to the stingers. And, even, finally, given up on the 4 blade in favor of the 2 blade.
Don't know what it is, but I am not a good sharpening person.
So, the 2 blade stinger suits me. It's within my inferior level of competence to maintain.
(I get a charge out of these folks who say how easy sharpening is, then tell me how to do it.... I've done it - and it ain't "scary sharp" on my shaft - I ain't got the go-juice to get-r-done.....).
Some day, after I retire, I'll try teaching myself how to sharpen, right after I get my brown thumb to turn green and stop killing all my trees I've been trying to grow.
