ok..
surly/open pro- $153
formula/deep v- $140 (iro)

i'm kinda torn between which i should get. keep in mind this is just for the rear wheel and it's only intended to be used on the street so which do you think would be the most durable. i have used formula hubs before and was pleased but i've had no experience with surly hubs. also, i just ordered an EAI cog and i remember hearing a while ago that there were some issues with threading and surly hubs/cogs as far as compatibility with other companies products..has this been worked out?
