I've been using adrenalines exclusively for years without any problems, but a few weeks ago I got bored and bought some structures and sequences as well to go with my adrenalines - I've been rotating all three types over the past few weeks and my initial impressions are that the adidas ones feel a lot faster and "bouncier" than the others, while the nikes seem to make a strange "slapping" noise when running on roads. I'm sure it's cos I'm used to the fit, but the adrenalines are the comfiest. I've not noticed any difference as regards new aches/injuries, but I've only run 60 or so miles on each so far....
They're just my thoughts though - i've got a friend who switched to nikes and got injured straight away, so it's a pretty individual thing...
