I doubt you're going to hear many, if any, complaints. Both are highly regarded. If you're shopping, the main thing to watch out for is if you are buying take-offs. I believe some of the OEM's put Bighorn 2.0's on that have a 2 ply rating. I can't remember specifically where I saw them... maybe someone else will chime in about it.
The Yamaha Viking comes with 2 ply front and 4 ply rear 2.0's. But they aren't even radials !! I found this out after buying a new set of Viking SE take offs. . No wonder the nice fancy aluminum wheels and tires were only $450 shipped for the set of 4.
Don't understand how they can be called Bighorn 2.0 when the real McCoy is a radial and the Viking OE is bias.
But I just lucked out and found a brand new pair of Bighorn (originals) 25x10-12's local for $150 !
So I think I'll buy a matching pair of 25x8-12's and mount them on my Viking SE wheels and use the "fake" 2.0's on one of our Foreman's or Rancher.
