there's a few out there, I've got a Hardy Sirrus 7footer, but have a look out for a shakespeare 'Excursion' - not to be mixed up with the spinning rod they currently make also called an 'Excursion'
they've stopped making them, but they are cracking little rods, just over 6foot, and six pieces so almost fits in yer pocket, full carbon, great action, but the butt section has a neat trick up its sleeve, it splits in 2 and reverses so it doubles up as a little spinning rod. They pop up on ebay quite often
Fladen do a canny 7 footer (ebay 170169910689), 3 piecer, good quality blank as well IMHO, for what they cost
there's always a few 7 footers on ebay
I use 6 and 7 foot rods quite a bit, but I never ever fish stockie still waters. For smaller rivers and burns they are tremendous fun, it depends on what and where the river is you're fishing, most of the english rivers I fish I seldom go above 8'6, if I do it's because sea trout and salmon are on the menu
