i am looking for aluminium advise..... predator recurve 29 1/2" draw to back of bow ...60# at my draw...am looking for 600 grains or a pinch more what would you recomend..... i would like to use 125 grain broad head....and possibly pdp weights but dont want to buy a bunch of different spines....any help would be appreciated...thanks

I would say a 2315 or 2216 would be my choice for that weight of  recurve bow.If you are looking for 600 gr range I would add some PDP weights behind the insert with the right PDP insert with the 125 gr broadhead.That would be my choice.A 2216(.376) and a 2315(.342) are within 10 grs of each other but stiffer in spine as you go up.You can probably tune all of them depending on their length.These are just some suggestions,with your draw length.

i see inserts that except pdp weights at three rivers for 2216 but not for 2315? so i guess i will try the 2216...thanks again
