I can't answer the question but here are my experiances. I just go a set and have about 3 weeks on them and two races. I am using 04 105. Lots of power and zero shudder. But the pads are set up very tight. I am worried about mud build up, so I might go to a travel agent to have more clearance,
If you can you may as well put as many adjusters in now and same time down the road.
