I don't care for double tab cause there are times i want to shift down just one cog on the rear and I find it hard. I cant afford campy and dont really care for the thumb lever, I like the shimano setup but try to stay away from the fanboi-ism. Honestly [engage flame shield] I tried a microshift setup a week ago that was honestly on par with ultegra as far as feel (for me) and the groupo was 450 bucks american. Roughly 500k korean won.
