Finally sorted the indexing on my 6700 Ultegra equipped Trek road bike. I'd fitted a Tiagra 4700 rear mech to use with an 11-34t cassette. After much messing about I discovered today that 4700 rear mech has a different pull ratio to all other Shimano 10 speed road stuff. I'd read previously, on older pages, that all 10 speed stuff was compatible..........Popped the 6700 mech back on and adjusted the L screw so it won't shift further than the 30t sprocket and its as sweet as it should be. Just need to order a 12/30 cassette.
