Current Projects chat and miscellany

My GT build has stalled momentarily. I'm keeping an eye out for some 10 speed triple STIs and found reference to Shimano R703s. My understanding is that they're Ultegra 6600 level, is that correct? As I was looking out for 105 5603s, I'm thinking these would be a good alternative, as they're heavily reduced at an online store (£128).

I guess I'm looking for some reassurance that these would be worth it?

you could always buy my complete ultegra 6603 groupset...
