hi GK, thanks for your post, and thank you so much for your kind words!
yes, i do mostly use the exl170's. i got a chance to play the balanced tension strings while they were still in beta and i thought they were really good. having said that, it wasn't the type of difference that had me leaning towards changing out my current sets. i've been playing 'traditional' tension strings for a lot of years now so i've been used to them for a long time. i can't say that in my development i ever said to myself 'gee, i wish i had more balanced tension between each of my strings.' however, i recognize the advantages and think it's a great idea. i was a d'addario user for many years before i got an endorsement deal and i've always liked the feel and consistency of their nickel-wound string sets. they have also always set up well on all of my instruments i've put them on.
i hope that helps you somewhat. like i said they are a nice set of strings if you decide to try them.
