I think to get that weight you will need a 340-350 spine and a very light shaft.The lightest will likely be a Victory V Force HV in .350 spine.
I shoot them cut 30" for 53# and use 430 grs up front-insert,point and footing,total weight,655 grs.
For your 10 lb heavier bow,deduct 50 grs point weight.Add 2" of shaft length(32")deduct 50 grs point weight.This gives you a 560 gr arrow with 330 grs point/insert weight.Of course you have to see what point weight works for you.
The Victory V Force HV shafts seem to need a little more point weight than a closely spined,say,Gold Tip.That's not a bad thing.They are also 6.7 GPI and .287 diam.The slimmer diameter probably contributes to needing more point weight.A 2013 aluminum will work for a footing but it is snug(9 GPI).They take standard .246 inserts and nocks.
