I ordered a new bow, it will be awhile before it arrives. I dropped down 10 lbs weight to work on form. Mainly to get my back muscles engaged. As my form changes for the better i know this will have an affect on arrow tuning. So its not really worth tuning until i achieve that. What do you do until then just buy arrows you think are close? I really want to shoot wood out of this bow. 45# @ 28. Currently draw 27 but with proper form will be 28 or slightly more.
If it were me, I would probably only buy a half dozen arrows at a time until I figured out what works best. A lot depends on the bow, whether it is cut past center or not cut to center, etc., as well as the way you shoot it. I assume since you're waiting, your bow is probably being made by a bowyer rather than a factory. Bowyers usually have pretty good ideas about what arrows shoot best out of their bows, so ask him too. Unless you have really crappy form, I doubt that your draw length will increase more than an inch as a result of training, but it will probably increase some. OTOH, my draw length is decreasing some as my body shrinks with age. I don't think my form has changed much, but my draw length as gone from 28" to about 27 1/4" over the last 5-10 years.
Thanks mcdave. Ive been watching alot of form videos and i know im not using my back when drawing a bow. With no weight in my hand i can engage my back and let my body tell me when im at full draw. Using back muscles like a draw stop. Letting that determine my reference in my face. Rather than just picking a spot. Doing that i gain about an inch. Its getting there with a bow in my hand that is the next hurdle
I use my back muscles like a draw stop too. Some time ago, I used that to determine where my face anchor should be. I use Arne's rotational draw to the point where I've reached maximum rotation, and at this point my string hand is about 1/2" from my face, which I believe Arne also does. I bring my string hand into my face and that's where my anchor is.
Interestingly, this doesn't necessarily determine an exact draw length. As I said, over the years as I have shrunk, and even though I use the same rotation and same anchor, my draw length has decreased. Also, when I use a heavier bow, my draw length decreases, not much, but a little. I think when I use a heavier bow, the extra weight pushes my joints together more than a lightweight bow does, and reduces my draw length that way.
