28″ or 27″ ITP Blackwater Evolutions – 1000 Outlander XT

My machine is in need of some new tires. I have been reading on the forums that ITP Evo’s run a bit small. They do have good reviews. I know there are differences in how to measure. Is anyone running 28’s Evo’s on standard stock Outlander? Interested if they are rubbing, loss of power, trimming plastics, puck lift, etc. Would also like to know if anyone is running the 27’s with same concerns. Also, any thoughts on satisfaction or dissatisfaction with the tire. Thanks in advance.
