Very well done bow!
Work it down to 49lbs at 23" and you'll end up with a great candidate for a flight- record, if shot with a light arrow( about 200-250grs.). 49lbs at 23" will match the rules.
I' ve an elm- shortie( 44" in length, 45lbs) shooting an 210grs. arrow at 224f/s.
Saplings rule! Michael
