I'd agree with Woodspringer on cost. I've shot both... prefer the Griz Sticks...but then I've been in on the development through a variety of trials with the developer of Griz Sticks.
I would only disagree on the comment about spine. I nearly lost all my black hair pullin it out and owe OL Adcock a debt for keeping me sane(well, as much as I ever was)
.
After much research, guys/gals, I've come to be 100% convinced that the "amount of center shot (center cut for some) of the riser dictates more about arrow spine needed than does the draw weight of the bow!
Griz AK's shoot weak for me w/ the standard 75 gr. brass insert and 125 tips out of a (ready for this?) Morrison recurve cut 3/16 PAST center. They're 29" arrows for my 28" draw. Yup. Weak! Out of a 54# set of limbs on the Morrison!
Verified by several shooters better'n me at ranges beyond my abilities using the bare shaft planing method on OL's website. They shoot beautifully if I shim out the sideplate some. Conclusion: centershot has a big, big impact on required spine of arrows to "tune" well.
I give same arrows to other guys drawing 28" like me and they're stiff out of their much heavier (up to 68#)draw weight LONGbows which are cut 1/8" SHY of center...big difference in center shot or lack thereof.
I've torture tested them for years in various "generations"/variations and they're as tough as anything I've shot. Sure, a glancing angle and yup..they're not indestructable, but I found mine to be quite consistent.
There was a period there where Ed's old mfg had some QC issues which resulted in Ed finding another mfg.
They're made to be "niche" arrows... aptly named for more dangerous game, but I do use them for just deer knowing that they "never fail" where I sometimes do.
