What YewArcher said !!!!!!! Stay off the fades and get the mid and outer limbs moving.
As far as the longitudinal grain I hope it is close ,if you can see it and it is running off the side
see if you can adjust the profile a little and match the other limb to it before you go to far on
the tiller,or you may concider backing it with rawhide.Some time if I have a little run off
I will take a chance till I get it pretty close to full draw and the rap it right at the run off with
sinew and usually won't give ant trouble.Then you can match the rap on the other limb and it looks pretty good.Keep us posted.
