Here's my 2 setups:
PSE omen 80lb 30" draw.
Sirius gemini 200 spine, 29" ctc.
200 grain insert, 125 grain point. Reflective wrap and super sabre vanes.
644 grain total arrow weight 284fps.

PSE Mach 34 80lb 30" draw.
Sirius supernova 250 spine, 28.5" ctc.
75 grain insert 125 grain point. Reflective wrap and super sabre vanes.

what were the limbs rated for?

80lbs.

 

[nguerrero5]

80lbs.

that's unfortunate to hear that they were failing. I hope I don't have any issues at 80

I shoot a Ventum 33 at 75 lbs, with 29.5" draw length as well.

Arrow is a RIP TKO 300 spine, 484 grains total weight @ 279 fps (80% let off). I'm happy with how the arrow tuned - I believe Archer's Advantage has it as "slightly weak" and the 250 spine at "marginal stiff".

Ya, I don't know if it was because of the long draw length or what, but every time a limb would splinter it would be the one on the bottom right (LH bow). I never had the same problem with the 70lb limbs.

I’m assuming I’ll be okay. I’m at 29 sometimes 29.5 but the bow maxes out at 31

 

[nguerrero5]

So I received the bow. I have it set at 29.5 but for some reason my draw weight scale is telling me it’s only 75lbs. Limbs looked maxed out and it says it was shipped at 80lbs

Sounds like it’s not in spec. Probably going to have to add some twists to the cables.

Measure the axle to axle and compare to factory spec.

Check your scale against something that you know is 80#, or 70 at least.

I have 6 different scales, only a few I actually trust.

Just saying this to double check yourself, don't count on a scale actually being correct unfortunately.

My hope is that the scale is off.

ATA is measuring 30 on the dot. I took it into the shop to just get a d loop and rest and sight installed. Planning on shooting a couple of hundred to get the strings settled and then will look deeper into it

How aggressive the cam is will have a lot to do with it.. I shoot a Hoyt vtm 34 at 83 lbs 29 inch draw. Spine chart on victory's website and podium archer says 300 Spine. Key is I cut my arrows short.. taw is 480 grains with 200 up front.. but my arrow is 26 inches long..
My Pse omen set up with 175 up front calls for a 250 Spine. Arrow is 27 inches..
The Hoyt is 334 ibo and I believe the ibo on the Pse is 356..

If you haven’t tried archers advantage is $10/year and allows you to put in your bow setup and mess with different arrows, spine, point weight, arrow length, bow poundage. It will give you an estimated speed as well as if the spine for that setup is weak or strong or acceptable. It takes some of the buying and trying out of the process. I have had multiple weight bows 60-80 lbs and like to tinker with arrow setups and the software makes it easy to get the spine right for what setup you want to try.
