I'm with Killdeer. I shoot both 3555s and 1535s out of my mid-40 bows. If you want to keep them fairly short, the 1535s will obviously be the lighter GPP; the 3555s you will have to load up pretty good.
My 3555s are 30.5" with 125 + standard insert + 50 gr internal weight for a total of 186 gr.
The 1535s are 29.5" with 125 + standard insert for a total of 136 gr. I'm thinking if I cut another inch off the 1535s (which I can't do with my draw length of 28") it would probably be just about right with a 150 gr point. Actually, there are lots of 140 gr and 160 gr broadheads so I don't think tuning it would be a problem.
And the 3555s could handle a 150 gr head with the internal GT weights screwed into the back of the insert if you want more penetration, or more likely, a 175 gr BH and some internal weight.
I'd be glad to send you one of each, cut to 28", and you can play all kind of weight games to see what works out of your bow.
Send me an e-mail if you want to try that.
