Been shooting a set of max6 limbs for a couple yrs now, love em!! Yesterday I had an issue, well in all reality the issue was going on it just finally came to a head yesterday. The string itself is only one year old, with several thousand shots on it.
Where the string contacts the limb I had been noticing the string looking a little rough. Well, yesterday, the string came apart. Looking at the other loop, there where more broken fibers. I've never experienced this with a string before on standard or static limbs.
Just wondering if anyone else has noticed the string getting really beat up on these super curves limbs??

I've not had that issue.
Pics would help us understand, and maybe determine cause.

 As you can see, the wear is a few inches below the loops, about the same on both ends |

Wow! That's crazy!
I can't for the life of me see how that is happening.
What material is the string made from?

DF 97 isn't the best choice of material, but it still should not be wearing like that. I thought about this all night. Even kept me awake some thinking about it.
I think/suspect, that you have a limb alignment issue, which is causing a lot of out of the ordinary lateral movement of the string in that area of the limbs.
That movement is creating a scrubbing of the string across the limbs, and the friction from that scrubbing is wearing down the string.
Can you provide me with four pictures of the bow?
1 - One of the bow unbraced looking square at the belly side of the limbs tip to tip.
2 - One of the bow unbraced looking square at the back side of the limbs tip to tip
3 - One of the bow braced looking square at the belly side of the bow tip to tip.
4 - One of the bow braced looking square at the back side of the bow tip to tip.
It's important to take those pictures as square as you can take them.
With them, I can do a grid alignment check to see "if" there is an alignment issue.

The scrubbing sounds like an accurate description. The reason say that, when I started playing with brace height a bit more that's when I first noticed it. Anyhow I'll see if I can rig me something to hold my phone to take pics with. Thank you Rick đź‘Ť

No problem Hutch.
I just hope we can figure out the problem, and get it taken care of.

No, I never see this. I had the MAX6 too and never seen that. The build quality might be at fault or the brace height + tiller combination.

I've got the brace set 7 3/4" I've played with it up to 8.25. Right now tiller is dead even. Been playing with that also, a little at a time. The bow feels good at the shot the best I can tell anyway.
I'm still trying to get some photos, having hell trying to keep the phone stable enough to get a sharp photo.

  I did notice the tips didn't seem the same. Sorry about the quality of the photos, my phone is pretty beat up From what I can see, limb alignment looks good. Again having issues with getting a good enough photo to share. |

Could you please say the length of the riser and limbs? Thanks. I remember Brandon had a recommendation for BH for each riser+limbs combo and usually up to 7.5” for “hunting length risers”.

Ya, it's a 17" samick discovery riser.
I vaguely remember coming across some info that said his brace runs a bit lower than a regular limb. I could be wrong though, that happens a lot. But anyhow, how are ya draven. It's been a while since I was active on the board. Lol
I've got another string on it right now. It's a bit skinnier. Braced about 7.5. It had a different sound and feel, obviously. But this string is wore out,lol.
Appreciate y'all trying to help figure this issue out
Hutch

How did you do the limb alignment?
I can tell you from experience, that the alignment on the Super Curve limbs is way WAY more critical, than it is on standard recurve limbs.

I've got the bieter limb alignment gauges. And yes I have discovered they are very critical. I've got em lined up pretty good but ain't gonna claim them to be perfect. I've played with it a good bit.
I've tried to take pics but my phone camera is to mest up to get a clear pic anymore
I appreciate y'all's help

Hutch, Brandon has a table for riser-limbs combo brace height on his web. Check there, under information / recommendations. Don’t go by guess and rumours.
If the tiller is not the issue I would blame the string built. Put some velcro where the strings leaves the limb and this should solve the noise and any slapping issue.

Just looked at his chart. I was at the way top end of his chart. I'm betting the harmonics of the limbs didn't like that brace of 7.75". The vibrations in the limbs ate that strong up. I had left it there because it shot good. It tuned at that brace but I'm betting it'll tune even better I bring it down
It's all good
Greatly appreciate the insight
Hutch
