Well, here is a boot camp question but if I don't ask, then I will never know the answer. I have 2 recurves: a Cravotta 47# and a Browning 57#, both of which I bought at yard sales. I also have a mixed bag of alunimum and carbon arrows I bought at an auction for next to nothing. Should I take a trip to the local archery shop and ask the pro to set me up with a set of wooden arrows for each bow or should I just continue with what I have? Frankly, when I shoot the alunimum Eastons the knocks dip so low to the ground after they clear the rest that the arrow resembles a WWII propeller fighter taking off from the bow of an aircraft carrier. Eventually the knock comes up and the arrow gropes its way to the target, but it's a sight to behold.
The same shaft will not fly well from both bows.
For the 47 pound bow you could use a Gold Tip 3555, leave it full length and use a tip of about 150 gr.
A CX Heeritage of about 30-31 inch should also work well.
The 57 pounder should shoot a 5575 or a CX Heritage 250 well.
Having the proper spine is critical to good arrow flight.
