I am still messing around with bare-shaft tuning, trying different spine and head weights, trying to find what flies best out of my bow. I doubt it is going to make me drastically more accurate (consistency of form and mental focus, not precise arrow spine, seem to be the big deciding factors for me) but it's fun and I'm learning a lot.
As some of you might have read in another thread, I had a 31#, 29.5" shaft that was flying beautifully from my bow. So I ordered a bunch more of that spine; most of them are flying too bendy. However, I have a certain 32# shaft that flies dead straight nocked one direction, and takes a hard left turn (too bendy--I'm left-handed) when nocked the other direction.
I've heard people mention this before, and now I know it's a real thing with the shafts I use. I have a new set of 40-45# shafts that I'm going to start trying out tonight, and I'll be interested to see if swapping sides has a similar effect. It only seems to happen when the spine of the shaft is otherwise very, very close to correct.
Anybody want to tell me more?
Cheers~
