Thanks for the input, really helpful.
Frankly i'm not too worried about performance, just the aesthetics! The bikes a track bike, with one front brake so it'll end up looking a bit silly if one rim is rubbed and the other not so much.
I have found, since new pads went on, that the wearing has got much worse (a marked increase in two weeks) hence wondering what might be a bit better. I've been keeping the pads clean though! In an attempt to reduce any wear.
