Had the penn 525 mk 1's, four of them, found them to be noisy and rough on the retrieve unlike the Slosh's/shimano speedmasters they were in competition with, so much so I sent them to Penn (Ewan in Scotland ?) to look at as I could not believe a reel costing what they were at the time could be so bad, ending up getting shot of them, stuck with the Speedmasters and Slosh's till the Silver Saltists came out. may have been me expecting to much from the reels, but truthfully found the Slosh's etc much smoother on the retrieve.
