I am running mechanical discs and just replaced my cables. I ran across the small adjustment blocks in the shifters. I read the warning on shimano's tech document, but I'd like to know if anyone has experimented with using them in and/or out and what I might expect.

Frankly the idea of easier braking power (which is what the tech document says will happen without the blocks) sounds good, but I'd like some other opinions before I take the plunge.

Thanks.
