adzi --dont be too impressed with sprog ( please just dont), there is a guy in americia that knows just as much
Jason, I think you are spot on re price. At £105 more 7's do and should last longer than PJ's. Performance is I think pretty much the same. Tho I am typing with a bruised and bloody finger as a result of uncompleted repair work on my 6-7 week old 7's hehe d'oh.
But things are ment to last and to wareout. Many peeps get bored and want somat knew for no good reason. I'd like hooves to last longer than they do ( but hey tyre sox or trainers are not too much to cope with). Springs ( if 1 gets the right model) 300 hours of use seems reasonable time for them to last to me ( inc pads that works out I think at less than 50 p an hour).
After 300-500 hours or even long before, peeps will be looking for something else. Just cos they do.
