mowhawks can be requested cut Very close to center shot. replacing the the arrow plate with thin tape (i like teflon tape) gets you even closer.
however and imho, it's not just weight of the bow or the "recommended" arrow spine, or the arrow build, it's you the shooter that's a large part of the arrow selection.
to that end, after you read all the charts, play all the software selection games, and listen to all the opinions, do yerself a big favor and do yer own testing. i prefer weak 29.5" shafts for all my mohawks - beman ics 500 (300gr up front), surewood 45-50 (190gr up front).
yes, if you can't beg or borrow shafts or arrows, you'll need to spend some dollars but they will be very well spent and will come in handy for future bows (no? no more stick bow acquisitions? HAH!
)
for woodies, surewood test kits are an Excellent way to trial out and figure what will work best for your bows and you.
