One set up going good, other having trouble

[inthebox30lbs]

This is what Im shooten.  Blackhawk Bee 42lbs at 28.  Im drawing 27.5 loaded it with a 29in.  35/55 goldtip with a 250grain field tip getting me close to 500 grains weight.  These arrows seem to fly just right.  Is this enough bow to hunt for pigs with, planning a trip this winter to Fl.
My other setup is a new Martin x150 50 at 28in.  Having all kinds of trouble getting arrows to fly out of it.  THe goldtips seem to be way underspined throwing them to the right.  I was told to try 2117 at 28 with 250 up front should work they fly terrible, any suggestions for this martin arrow wise.
 THanks for any replies.

If they're weak spined, try a lighter field tip.

You could as bmfer said lighten the tip. You could also trim the shaft. You have some room to work with and carbon is pretty sensitive to trimming. Go 1/4 inch at a time. Another way to use the GT's would be to build out your sideplate, effectively stiffening the shaft.

If you don't mind changing shafts, 1916's fly great out of my 46# Kanati at my 28" draw. That is pretty close to what you are going to be drawing. I shoot 29" shafts with 170 grains up front. Another alternative would be 2016's with your heavier point. I like the thinner arrows. 21's and 22's look like fence posts to me.
