2011 ski doo renegade back country 600 ? need help

so im looking for a new sled, i currently have a 08 polairs iq 700, absolutely love the machine, i just want to do more powder riding and breaking trails. i seen a 2001 back country 600 for sale with just over 6000 miles, the guy said the previous owner had said it was rebuilt at 5000 miles but hes not sure, it has 130 psi compression in one and 134 in the other cylender. my question is this, how powerful is the 600 ? is it gonna feel alot slower then my 700 ? will the 137 be good enough for deep 2-3 foot deep powder ? and whats the life expectancy of the 600 e-tecs ? not sure for the year but i always hear bad stuff about them blowing around 5-6000 miles, any help is appreciated just wondering if i should get it or wait until i can find a decent polaris 144 for sale
