I just came in from trying old arrows from my go to bucket(100s of old arrows) tryed all w175grn tips and found 2013s 2018s 2114 and the war horse 2117s. (But no 2016s darn!) The best were 2018 30 inch(had 2) and 1@ 29 the 30 seemed to fly great till I tryed to bare shaft(way left,rt handed, but grouped with my carbons)2013s@28 took off like rockets but were way light, noisy bow. the 2117 full length looked good but at 29 inch hit the risor with a clang(stiff?)and went left.I have lots of 2117s so I will revisit them. so looking for 2016s to try and maybe 2018s hmmmm... so meny arrows so little time what fun!!!
