ive found out that my 07 ally really likes 2314 shafts but i cant get them down light enough for 3d also. i would like to set it up for indoor and 3d. i was wondering if 2312 would be a big spine difference then the 2314 and the bow might not like them as well. im shooting the 2314 at 27" with insert and 125 grain for indoor and its a super forgiving setup and i can get 50grain glue in nibs and cut the 2312s down to 26" if i have to and that should be around 350grains. the ally shoots 290 with my xcutters at 62lbs but they are super stiff and dont fly real well past 30 yrds. thanks for the input and responses.
