Ok so here is my problem. I have a 2011 Rush LX that the wife drives. She complains that it fish tails too much and slides around corners too much. She is not an agressive rider at all and really dosen't like to lean too much going around corners and such. I believe it has a 1.0 Ripsaw track on it. When she rides my 2012 Adventure with the 1.35 Cobra it runs straight as an arrow and she loves it. I know the longer track and deeper lugs is the difference here, but I just can't see taking a hugh hit and trading it in on a Switchback for her. I can get a 1.35 X 121 Cobra for her sled for about 400 bucks. Do you guys think this is a worth while swap out to help the sled hook up better and fishtail less? Like I said before, she is not a real agressive or fast rider, just wants to feel more in control. I just can't see sinking in another 3 grand or more to boot for her to ride a sled about 3 or 4 times a season. Any thoughts?....
