Do y'all think a Beman .500 cut to 30 and 1/4" with a 100gr brass insert(275gr up front) and 175 gr field point would be similar in spine to a 29" 15/35 Gold Tip(.600) with a 145gr point.I have a 45# Centaur and am wanting to shoot both of these out of this bow.So far,the Bemans shot well with wide broadheads at 15 yards.I haven't had a chance to shoot the .600's yet.I plan to hunt with the Bemans and shoot 3D and maybe hunt with the Gold Tips.The Bemans weigh 522gr and the Gold Tips weigh 412gr.
Personally, I'd switch roles for those arrows. I like my 1535s for 3-D and the heavier .500s for hunting.
I don't know if they both will work or not, but I agree with Bladepeek that the heavier arrow would be my hunting arrow.

I may have said it wrong.I plan to hunt with the heavier arrow for sure and use the lighter arrow for 3D and possibly for hunting.I'm just wondering if anyone has any experience with using both .500 and .600 shafts out of 45# bows.

I rather thought that's what you meant :)
To answer your question, I don't think you will have any problem at all.
Your specs will be slightly different, I'm sure, but I can shoot 30.5" 1535s with 155 gr total (points and inserts) and 3555s, 29.5" and 235gr total (points, inserts & internal weights) from the same mid-40# bows. Out to 20 yds or so they even shoot to the same point of aim.
