Anybody end up buying the 129 track and extension getup? I have enjoyed the 120 convex thoroughly but I'm a big guy so I could use some more track in the bottomless pow. I have been thinking of just putting the convex up for sale and making the switch if someone buys it not totally sure what I should be asking for it though. Also just wanting to make sure the rail extensions aren't going to snap in half. I have rode with some guy's on camso and the traction was remarkable, I realize it isn't the exact same track but if performance would be similar i'd be a happy camper.
