I have seen posts on other sites about some bad smooth on and another  product to use instead of smooth on. Its  called huntsmens TDR 1100-11
Has anyone heard of any smooth on problems?
Or huntsmens?

There have been a couple reports of ea 40 failing, one in the USA that I know of. I know no firsthand info on the huntsmen .

A couple reports in how many thousand bows isn't too bad an average, but it sure sucks for the guys who had the failures! This because I don't think the bows failed immediately so they had several out before it became evident.
