Not an expert but I have always used the 10 grn/# formula. For example I shoot a gold tip 5575 at 30 inches long that gives me a shaft wight of 270grns. I add 10 inches of 5grn/in internal sleeving (footing)to produce a weight FOC arrow, bringing the weight to 320. Add a 150grn broad head, 470grns, and fletchings and your real close to the 500 grn target for my 50# recurve.
Might try a 7595 full length,352 grns. Add 10 inches of 10 grn/in sleeving, 452. And tip with a 145grn head, 597.
