I shoot a non fast flight recurve that is cut to center and 57# at my draw length of 27". My broadhead will be 207 grains once I glue in the adaptor and I hope to have the shaft cut to 28". I have a chance to get a good deal on some CX rebel hunters and would like to know if you would go with the 45-60 or 60-75 and if I should use the 50 or 100 grain inserts? I know there is nothing exact about this but am looking for a place to start.

Just guessing here, but I would go with the 60-75s and a 100 grain insert. If you have access to a cut-off saw or you are close enough to get to a shop that can cut them, I'd bare shaft them starting with 30" or so. If you leave 'em a bit long you can always work your way down until you've got the right combination. Best bet would be to buy one shaft of each size and work from there, but if you are mail ordering that could be a pain. With a centershot bow and over 300 grains up front (200 grain head + 100 grain insert) I am GUESSING that the stiffer of the two will work for you. Good Luck>>>-------->

The 4560 CX Hunters spine equivalent is 79#
""  6079 "    "     "     "      "    " 92#

I would go with the 4560s and add some weight with inserts.  For instance, I shoot a cut to center recurve 55#@28". I shoot CE 250 Heritage shafts cut to 29.25", 100gr. inserts and 125gr. tips. These shafts have an equivalent 84# spine weight. They bare shaft great. Start with the 4560s at 30" and cut them down slowly...1/4" at a time. Use plastic wrap in between the insert and the shaft to hold them in while you are shooting and cutting them down. That will hold them in place. When you find the right length with the tip weight you want to shoot glue them in!

For carbons on trad bows I don't worry about the length that I end up with.Ending up with a 28" carbon arrow can be a hit or miss.Carbons don't come in as many spines as wood or aluminum,you adjust the dynamic spine by trimming the length or adding weight up front.You can most likely tune both of them to shoot fine out of your bow.The 60/75 you will most likely need to add a 100 gr. insert,the 45/60 might not need a heavier insert to tune with a 207 gr. head.How heavy of an arrow are you hoping to end up with? I would choose the 45/60 and tune from there.

I shoot a MOAB longbow at 63# and Beaman ICS 400's work well when I play with them.  Mine are 29" with 100 grain brass broadhead adapters and 160 or 190 grain broadheads.  They fly very well.  I would thing the 45-60 would work better, but I'm a wood arrow guy, so take it for what its worth.

Thanks for the replies guys. I think I will stick with my ash or birch shafts for now.
