I have sava's on some of my bikes and IRC's as well as gazelles. I like all 3. Sava's for semi slicks are good in the rain in my opionion. Gazelles are too. In the end ,Gazelle's are a great tire in all circumstatnces, but shit man, id rather put a sava on any day.
I think alot of sava bad press got generated by a bunch of people dumping some old ones on ebay and the like. A new set of sava's is one of the first things id rec. for anyone with a bike looking to upgrade for rideabliity. Easy on, great tires.
Ive put a lot of miles on a set in a couple of years..and have been impressed.
Its all what ya want.
