Yeti SB130 Lunch Ride.. Why I made the switch. Is it worth the money?

So I bought a yeti SB 130 and absolutely loved it. However as I became more comfortable on the bike and as the trails became more aggressive, I started to question whether this was the bike for me. My friends were laughing because I was starting to choose XC trails versus the normal chunkier downhill trails and I had always enjoyed. I noticed that on serious chunk and bumps my SB130 would seem to slow down and/or get knocked off line. I had heard rumors of what the industry calls the lunch ride version, and decided to investigate. The word on the street was the employees at Yeti in Colorado do a lunch ride every day and some of the employees that ride the SB130 have upgraded. They take a stock SB130 and change the suspension from 130 in the rear to nearly 137 and also upgrade the front suspension from 150 make it 160. With what I was experiencing on my SB130 this seem like the perfect upgrade. I am an average rider, on an above average super bike. I am not an expert about suspension, but I do believe I know how a bike should feel. These are my thoughts and impressions on whether or not the yeti SB130 our upgrade is worth it.
