I have no experience with either tire but I have often used different brands on the front and rear of various bikes and never had any issues doing that.
Hi klaviator, thanks for your comment. I really appreciate that you took the time and shared your thoughts.
I just ordered them, taking advantage of an unusual price matching deal from a well-known specialized store (they usually price-match only against US-based stores, which makes sense. This time apparently they made an exception... inadvertently, I'm almost sure.)
Anyhow, I'll post the results of the experiment after I had ridden a few miles with them.
Thanks again, and ride safe!
