I should add the ones I got are great quality, fit, finish & components. I read in a review that the insert fit in some of the early shafts wasn't good, but mine fit true.
They are also the best looking wood grain finish I've seen on a carbon, I used ex-fine steel wool & removed the label & they look even better. imo
I like to shoot 125gr-150gr broadheads & I'm not into extreme FOC,
These shafts will get you to the hunting weight arrow you need, 590gr for my 28.5" 500's with just the stock 50gr insert and 150gr broadhead & I like that about them.
