Been awhile since Ive owned a D-style bow, just traded for a Northern Mist Superior 51@27, Im drawing it 28 1/4 or a tad more...believe the string is a FF string of some sort not sure what, also have B-50 string for it...what aluminums or carbons should work at this draw length, tried 29.5 in. 2016`s w/260 gr. up front, arrows hit dead center but fishtail back and forth a little, 35/55`s same length w/280 gr. up front a little better but still not right. Brace is 6 1/2 in., played with it from 6 1/4 up to 6 3/4 and arrows still fly the same.
