I have the STS13PM, and very pleased with it I am. I think it will certainly get a lot of use for a long time to come. For me it falls nicely in between my clean ground and very rough ground rods, but at a stretch it could cope with most scenarios.
I don't see it as an out and out rough ground rod (telegraph pole), and is much more forgiving than, say, a Greys Apollo, but not so floppy that it folds up when dragging in fish/weed through snags. As with all Diawa's, the butt has quite a large diameter (which some people don't like). Strap a 525/slosh on with 25lb line and it is ready to go into the snaggy ground. Strap an Abu 6500 with 15lb line and it isn't overgunned for clean ground. As an all round rod it is certainly versatile and reasonably priced. Dump the coasters, fit a screw winch reel seat and off you go.
