One of the great things about recurves and longbows is the average person doesn't have to worry about the right size. The only thing that changes with draw length is draw weight. The further you pull, the more poundage you get. The standard for adult bows is to mark the poundage a bow pulls at 28". Pull less than that and you get less draw weight. Pull further and you get more.

Most folks say to just add or subtract 2-3 lbs for every inch over or 28". The old rule to more accurately estimate poundage is to take the draw weight marked on the bow, divide by 20 and multiply that by the number of inches your draw length varies. Your bow is 45 pounds. 45/20 = 2.25... So, if you draw 27", then 45-2.25= 42.75, or just under 43 lbs. If you draw 29", then it'll be just over 47 lbs.

That's probably more info than you wanted, but it's good to know such things.

Your bow will be fine for deer size game and smaller. It might get you by for elk at close range, like 20 yards and under, with cut on contact heads like the Magnus Stinger.

Some other arrows to try would be Carbon Express Terminator Lite 4560 or GoldTip Traditional 3555. Feather fletch, definitely.

Shooting off the shelf is the way most traditional shooters do things these days. Nothing can be simpler, once you get tuned up right. Your arrow rest will never break or move unless the bow itself breaks.
