Favorite Yeti you rode? I'd love to get some time on a SB6C.
I started with the SB6C and it was a lot of bike for the trails. I never felt like I was even getting close to its potential on the trails there and could never really let it rip. The tires were also pretty slow rolling for those trails. Overall, it was amazingly smooth and I just kept looking for bigger and bigger things to hit. It felt like a tank. I would love to ride it again somewhere in the mountains like at the bike park in Crested Butte.
Then I rode the SB5C and WOW! That thing was unbelievable. Super playful and just felt more alive than the SB6C. If I hadn't just bought an SB66 and had the money, that's the bike I would go for. Probably not a 1 bike do it all, but pretty dang close. I was riding it and didn't realize it was only 127mm of rear travel. I thought it was a 150 bike on downhills and a 110 on the up hills.
Then I rode the SB4.5C after a friend pretty much forced me to as I'm not a fan of 29ers, but once again, I was blown away. The rear chain stay is actually shorter on that bike than the SB5C and I had no problems cornering or it feeling to tall, and once again, I felt like it had the same travel as the SB5C, but it only has 114mm of rear travel. I'm not sure if the tires had more air, or if the suspension had a little more air or if it is due to less travel, but the ride was a little more jarring than the 5c, but still super confident dropping off ledges and getting into the air.
