It's not a very stable frame in stock form due to the low SW. You need to weight it up and then it plays like a more comfortable 2013/2015, IMO. It's a brilliant stick and for those who wanted something similar to older generations but a tad more arm friendly, it's the one. However, In stock form it's horrible (for me anyway due to SW <325).
If you loved the V7 and were not a fan of older generation 'stiffer' blades, then this is not the one for you. It is definitely stiffer/crisper than v7 (giving more power) but because of the increased stiffness in the hoop, ball pocketing suffers slightly with the same string/tension when compared with V7.
All this is for 18m btw, I have not tried the 16m and have no interest in trying it.
I have not had any arm issues with it yet and will be switching from V7 to this V8. However, I will keep the V7 incase this gives me arm issues in the future.
