G'day

I have decided to upgrade my standard brakes on my Surly Long Haul Trucker with Tektro RL520 levers as suggested frequently here and elsewhere.

My question is to which v-brake to marry them to. From what I have read the Tektro 857AL has been the recommend v-brake in the past in part because of the mudguard clearance (I have mudguards on the Surly). Is this still the best option?

Also I assume that with the levers and v-brakes there are no other components required for a retro fit?

Thanks
Andrew
