A co-worker has a pearson rogue bow for sale it's set a 29" pull, can these be adjusted? I've never owned a bow but Know i will need a longer pull. It has sights, quiver, hard case, and about 15 arrows with a bunch of field points and broadheads for $40. How far back does the string have to go anyway? I can pull this one back and the string is almost 2" from my chin? :roll:
