I started out shooting longbows, but switched to recurves about 10 years ago. This year I decided to pick the longbow back up. I wanted to shoot wood, so I bought 3 dozen of the closest matched wood arrow I could find. I made them up, then spine and weight grouped them. I was shooting 65,66,67 spine and they were all within 10 grains. I have been shooting them for the last few days. I was not getting my usual tight groups. I kept shooting and fine tuning. After all that work I expected my accuracy to be as good as it had been. No matter what I did I could not get them to group like I wanted. I went in and grabbed 3 2018's that I thought would fly good. Went out and shot a nice tight group. I like the look of wood arrows, and they were fun to build, but I am going to stick with my aluminums. Every arrow is the same spine, weight and dimensions. I wanted to shoot in the longbow class next year at the state shoot, but I would have to shoot woods. I guess I am going to just shoot the longbow in the recurve class. I have always said that you can shoot well with a cheap bow and consistent arrows, but not with a great bow and cruddy arrows. I know years ago when I switched from woods to aluminums my scores went up by at least 20 points.
