48# at 28,  my draw is 27.5 (so about 47#)  .....  Easton Carbon Legacy 500 spine at 29.5 inches.  175gr VPA 3 blade, 75 grain brass insert.  (3) 5inch shields, 7 inch wrap, super 3d nock..... total arrow weight 530ish.
I may also try in the woods this year,  same arrow, but with older 165gr Simmons non vented interceptor epoxied to 75 grain steel insert.  Shot this the other day and they fly fantastic.  And I've never put a Simmons on a deer and want to.

I'm still young(71yrs), I still shoot 50+#, 30" draw, VPA three blade, around 560grs arrow. Don't know the gpi.   

The one I weighed went 596 grains,footed with purple heart and has 2 blade Delta 29 inches to back of broadhead slung by 51# Wild Horse Creek Destiny.Not much noise when I turn one loose

This year's elk arrows are Lodgepole pine and with a 160 grain Ace come to around 650 grains out of my 62# Hill Longbow. Also have some boo that shoot well which are 600 grains finished weight.
