I recently bought a pair of e41 750i's and love them, but unless you live in Australia I don't think I can be of that much help to you, sorry.
I am one of the fussiest people when it comes to gear, but the E41 750 Pads are among the best I've used. I was PREPARED if I have to, to spend the top line to get the right pads, but these were far more comfy, light and fitted than any of the other pads.
I would be comfortable recommending them to someone who was buying online. If not, Id definitely recommend the E41 pad range (is it available in the UK?), as all their pads are good.
