Actually Ryan, I know for a fact that once the limb is balanced Guava would never collaps, the patch is more just extra insurance, and because I don't want to see it
this one Guava with Huge frets, I bended to 45 " on a thread here on PA, and it finally gave up on the back but never changed on the belly
I have a couplle of other ones of from my beginning with frets, that hunted a lot and still never changed
