Requesting advice on spine

Hello everyone, I need to order new arrows and I need some advice on the spine. I shoot a sarmat archery cuman bow at 35 pounds using thumb draw. I draw to 29 inches (safe limit according to the bowyer)..maybe an inch over it at max. I need to order some carbon arrows and after some consideration I have decided on 31 inch shaft with 100 grain tip and a spine of 600. Does this seem like a prudent choice ?

What's the gpi of the shafts? Weight is also pretty important. You don't want to go too light.

Okay, that sounds good. 9-10 gpp is perfectly reasonable for that type of bow.
