Another mud / trail tire question

Guys, I currently have my factory big horns that are 26’s and I also have a set of 29.5 terms. I am tired of switching them out and now that i have the Outkast lift on I think a set of 26’s will more than likely look funny. I really want a good all around tire, but runs good in the mud since most of what I do is mud.
I am really looking at the intimidators, I know several folks with this tire, but they are running them on 1000 4 seaters and 36" tires at that.
I am torn between the 30’s and 32’s, there is a 6lb difference between the 2 sizes at 52 & 58lbs. I am wondering will that 6 lbs make a huge difference as far as the life of my front diff and other parts.
I am also wondering if there is another 32" tire that compares to the intimidator but may be lighter.

I am running a 2013 800s with an Outkast lift, I do have all aftermarket axles, and I have stock clutching which runs fine with my terms now. I don’t run fast and rarely get out of low gear.
