If that's what you're asking. If not, carry on.

Thanks KRS!

That's great to know because I just found out today that I find Tiagra hydraulic levers to be extremely ugly. Dealbreaker for me XD

I also since believe I've seen that Shimano's compatibility charts confirm your statement.

New Super SLR is slightly different from SLR-EV. By Andy's measurement EV seems to have more initial cable pull and about 10% more final mechanical advantage than "New".

When mixing and matching lever and brakes, the added flexibility might be handy.

Unfortunately Shimano's product page lists the 4700 as both "EV" *and* "New". Argh!
