Well, i got to use my new spin jag today. It really worked great. I was shooting my Omega and it has a QLA, if I had been shooting anything else that I own, the fiber washer would really have provided extra protection to the crown as I was pushing (using the jag like a short-short starter) the sabot and projectile down the barrel.
Another plus was as I was pushing it down there was not torque on the the range rod - the sabot twisted its way down without trying to twist the range rod.
While running patches - I could NOT break the old habit of tightening, or least trying to tighten the jag in the range rod.
It is expensive, at first, but I think over time and as much shooting as do it will easily pay for itself....
