Well... I was doing everything as slow as I could, to see what was happening (I did a bit more shooting in my yard). It's definitely the strings that hit my wrist (base of the thumb, at the notch, where a wristwatch goes). So aside from hiking my armguard up and keeping my watch on, I can't seem to make that stop.

As for the second issue... it might be... though all of the arrows do it and they're all new. I thoroughly checked each arrow for any problems before using them, and hadn't noticed anything. I tried changing my stance up a bit, and hand placement. I was able to get maybe 30% of my arrows to fly perfectly straight, so it might be that. But, then again, I'm now focused on the issue instead of not noticing it right away before. Maybe someone has heard of this happening.

Oh, and I do notice every one and a while the arrow passes over my hand and the fletch knicks the meaty part of my thumb. I figure this is normal, and doesn't hurt in the slightest. It's the damn string to the wrist that bugs me the most.
