has anyone put a long track kit on

[apex#1]

i have a 08 apex gt and was thinking about putting a long track kit on but unsure on what size or from ulmer or hartman. I mostly drive lakes and groomed trails but i also love breaking trails and getting in the deep stuff. The 144 kit from ulmers sounds interesting because of the tipped up rear end making it a 136 till you go off trail but i dont know if a need a 144.
Any info or feed back would be helpfull on making a decision. Thanks

I;ve installed the Hartman 136 with a Camo Intense track. Lots of hookup.
