Ask your shop if they can custom order the intiution liner for you. I have Krypton Rampages from a few years back and got the intiution liner for them. I don't think there is much difference between my current setup and the newer models you mentioned. Doing this could save you a good chunk of $$ by getting an older Krypton, or any of these models, with a worn out liner, and getting a brand new inuition through your shop.
I believe the liner cost me somewhere between $100-150, that + an old boot which you would just use the shell from would run a lot less and fit the same as the newer models.
