This is for my Tassajara I use for commuting.
I'm looking at the Specialized Nimbus Armadillo 26x1.5 and the Specialized Hemisphere Armadillo 26x1.95.
I'm wondering which would be better for commuting on streets. I did have some trail in my commute but i don't anymore unless i need to hop a curb or something. I'm choosing between these two for their armadillo protection.
Basically one is narrower than the other and the tread pattern is slightly different (which i hear doesn't matter anyway).

Also, I already have one new Hemisphere that I will be pairing with which ever tire I decide on here. So if I end up with both of these tires, which should go on the front and which on the rear?
