If you havent experienced a big hp yamaha I think its well worth a try. If you have your eyes on the big chutes they are second to none. Its kind of funny how you say your sled is predictable and maybe getting a little boring. A turbo yamaha is on the complete other end of the spectrum. Maybe a little unpredictable with the insane amount of power they make. Really for a lot of people Its not the weight but the power and harnessing it with the right suspension/boost/rider/ experience is key. For some its just to much to handle. Some get it and and learn how to tame the beast. Some don't.
"Taming the beast" is a fountain of neverending fun and Zeb is right..... it is not for everyone. Taming the ProRMK... well I think women and children can do it! JK!! I want a RMK too, as a backup of course....... No offense to the women and children btw!
