I would like to fletch some cedar blanks. My question is, how do i know what spine to order without having my bow done. I know i'm probably going about it backwards but i can't work on bows in the small confinement of an apartment. The only help i can be is that i draw 65 lbs @ 29" on a custom kodiak t/d, and would like to end up with an osage self bow around the same draw weight, only non-centershot. I'm not sure if arrows are appropriate in the bowyers bench, but any input would be helpful nonetheless.
