Replying to Packing out full tilt liners

so how long does it take to pack out full tilt liners? ( the TW 2014 in particular ) and also how much room will it give me when they pack out? maybe a half of a size? just wondering because i just got the TW in a 26.5 and they are pretty snug in the toe box. but i tried on the 27.0 and it felt good but i could slide my heel around ever so slightly. so i went with the 26.5 because everyone said the liners will pack a bit and the liner will mold to my feet more. (note. i did have the liners heat molded at the shop) also im getting super thin performance socks to help with this but im assuming the liners will pack to feel to super comfy.
