If you were not already aware...... as discussed on ADV rider, some have been using Achilles ATR-K Economist (~$50) but apparently not the greatest, and the newer on on the block is the Bridgestone Potenza RE040 in the 175/55R17 size (~95). It has a more rounded profile..... anyway, interesting option. They are hard to find, but have been around for a couple of years (maybe in Oz first?). There are some on ebay but 2015 manufacture if that concerns you.
