Great review Christopher! Sounds like you've raised a couple of awesome boys as well! Can't wait to get my new 850 out and compare it to my AXYS. Have had Polaris now for some time and have been very happy with them. Last year was a serious game changer with the AXYS and am anxious to put the Doo and Poo head to head. I, like a lot of riders have always hoped Yamaha could be more competitive in the mountain segment regarding weight, but they're just not there yet. They build a great quality sled, but as I've said in other posts, and have adamantly disagreed with you regarding the weight issue, they have a way to go. Am so glad to hear this is such a passion for you and your boys. I know in the forty three plus years of riding, I can't ever imagine giving it up. Looking forward to your future reviews. Until then, take a deep breath of the two stroke smoke, it's kind of addicting.
