Best Arrow Weight for Low poundage bows?

"To each his own but I love this setup, and am taking it to Africa in about 4 weeks."

That's what I'm talking about.  I'm taking a 50lber slinging 650 grain or so splinters of death. I always advocate shooting the heaviest bow you can accurately but with a pair of tore up shoulders it's nice to be able to optimize my set up with a heavier arrow.  What broadheads you shootin shortstroke?

[shortstroke 91]

I shoot Razorheads (2 blade), Grizzlies and Woodsmans. All 250 grains on top of a 100 grain brass insert. 350 grains up front.
