Original Bighorns or Blackwater Evos??

Hello everyone, new to this forum and looking for advice…..I have a pretty well stock 2011 Grizzly 700 EPS. Lookin to upgrade the crappy factory tires but keep my stock rims. I am torn between the Bighorn originals and the Blackwater Evos. I am also undecided between 26" or 27" size. I am a trail rider mainly on a wide range of terrain types but no extreme mudding(not a big mud fan) but trails can get sloppy at times. I would really love to see these tires/sizes on you alls rigs. Main concern is good clearance with no rubbing…..I do plan to install the 1.5 shim with tires to bring gearing back. Will the bighorns feel "lacking" when it really gets sloppy? Will the Blackwaters feel stiff with their 8ply? I have thought of putting the 27" bighorns from my yxz1000r over on my Grizzly just to see, but they are on 14" wheels and is a lot of trouble……Thanks.
