newer model

I have a T300 now and was wondering if anyone has any experience with the newer models. Was looking to upgrade to a newer model. Have standard controls now and how do people like the switchable ones? Seems like after a full day I am worn out. Want to stay with same horsepower or maybe bigger? Thanks

The hand controls are fancy, but when they go bad, they can be a a real nightmare. Parts are expensive, generally the dealer needs to hook a computer up to it as well.
I have no experience with tracked machines, hopefully someone will put their 2c in shortly.
I know what you mean about the controls wearing you out, i have found it takes a lot more work to drive my S150 than my old 743. I think it's mostly due to the addition of shock absorbers on the controls, there is a lot more restriction there.
