I fletch all my arrows at the most offset I can get and still maintain good contact with the shaft. Don't have anthing to measure degrees. I'm using 2" Blazers. As far as the broadhead weight, I generally use 100, 90, and this year went to 75 gr 3 blade Muzzy's. The 75 gr worked flawlessly. Took a 142" 11 point and a doe. Both expired quickly. Must admit I wasapprehensive about the 75 gr but it did it's job quite well.
