Hi Kurt, these liners will work in your T1. You just want to ensure that when you mold the liner you flex the toe bellows a couple times to ensure that you create the flex zone in the toe of the liner.
Hey Mike! I'm definitely not the leading authority on the T-2 as we've never stocked it so bear with me. Overall I think the Pro Flex G is probably a pretty similar liner to what your T-2 had in it and probably one of the best replacement liners available. They're fairly stiff (Medium or Medium Hard maybe) and seem to have a pretty tall cuff.
Hey Jonathan! Nope, they're from the Maestrale! They're a bit shorter in the cuff, thinner, and have better walking capabilities, but it comes at the expense of stiffness in ski mode. The Speed Ride Liner is the original Freedom SL liner that you're looking for, but the Intuition Pro Tour is another awesome option to consider, especially if you spend a bunch of time skinning in those boots.
Eric-Depends on which liner you choose. The pro-tour medium volume and low volume are different thicknesses. Both the pro-tours will have a stiffer cuff than the proflex-g and will add some support to the boots. The proflex-g has a thinner toe area but probably the thickest cuff of the three liners. Otherwise the Low volume pro-tour is the thinnest liner of the 3 overall.
Hi Luke, it depends on your fit. The Alien liners are a lot thinner so if you didn't have much room in the shell they would work great. The Pro-Tours are thicker, heavier, and don't articulate as well.
