They're a whole lot more compliant (but not as compliant as the SQ Labs I have just take off the Solaris). I can ride the Surlys on the Murmur but not on the Solaris - some of that maybe the fork - Öm2 coil v old Pike. Shape wise they're not as nice - there's something about the shape of the Surlys that's really nice. I'm still thinking a Hunter Smooth Moves in 75mm rise is going to be the best of both worlds.
I'm planning on getting some Toxic Barbie Burgtecs burgtec.co.uk/product/penthouse-flat-mk5-pedals and put the purples on teh Murmur. Will probably add a few more pink parts - but not go over the top.
