I am no expert, I just think the spine charts don't take the weight out front into account very well. I am 28.5"/72# and am in a 250 spine because I have a 100g head and another 100g outsert system.

I'm not talking about spine charts. I'm talking about a computer program that takes into account all the different factors that impact dynamic spine, as well as practical experience with the setup I mentioned, and my setup requires a stiffer arrow than the OP.
