Cal, I wouldn't know how the F my bags are doing - haven't towed the boat since February.
The good news is that baseball's almost over, and we hope to hit Havasu July 15-16 and July 29 through August 6. Hopefully we'll get another long week over Labor Day and a couple short weekends. Lots of making up to do. On track to miss my already horrible 40 hours/year.
No, so far no problems with the bags, and I think they're really pretty cheap, too.
