2009 Adrenaline 121 to 137 track upgrade

Thanks.
Roughly calculating 600-800 USD + replacing.
I think better option will be Summit with 146" track than playing with track replacement.

I have option 2010 Summit but with 600 E-TEC engine. Price the same. Won't be too weak ?
It's just 10HP difference and 600 should be lighter so there should be no significant difference in power ??

I have found one more - AC F8 2009 with 136" track Price the same as Ski-Doo 600 E-TEC Summit with 146" track.
Ski-Doo is convincing me with Rev-XP platform where I can mount additional seat and occasionally take my daughter for a ride. Arctic Cat doesn't offer such an option.

get the etec they are way better 20 miles to the gallon with those 600 and they have more punch then u think
