So . . . some questions.
Why did it break at the stabilizer bushing, right along the glue line ? Your bow reel was not the type that is installed there.
Although they call it a stabilizer bushing, I haven't seen anyone hang a stabilizer there for YEARS. What I have seen is folks installing bowfishing rigs. If it so weakens the bow, why did they install a bushing there (I am assuming they did it and not you, as aftermarket). Also, that break sure looks like it backs what you were saying, the stress was on the handle at the pivot point, while under stress of shooting.
I personally think the wood handle bow / bowfishing statement is a crock. Nearly everybody that shoots a stick for bowfishing uses wood.
Seems that they are just not a company to stand behind their products. Sorry your bow broke. I suggest another builder.
I won't be buying anything that says "PSE" on it. I am personally getting a bit tired of BS handed to us by manufacturers turning out a bad product, then claiming it is out of warranty. It is either a good product, or it isn't. You will stand behind it, or you won't.
