Pros: Easy to fit, heel hold excellent, good performance
Cons: Cold toes
Great fitting liner and good performance. Lace up tongue give solid all around fit and with the power strap keep shin in contact with the tongue. The spot kit would help with tweaking those spots where you need a bit more fill for leg shaft, and around heel cup and low instep. Depending on your shell can be hard to get in and out. Using a silicone spray on the shell will help sliding the liner in and a boot heater bag will help warm them up to get both in and out as well. If you use a plug liner like I do the lower can be very stiff and not user friendly with any lace up liner.
I have some cold weather issues when it's below -10C. When i come from a warm room to the cold I get moisture on the inside of the shell and the neoprene toe box gets wet and then cold. I used a plastic bag as a barrier and this stopped the issue. I also have boot heaters but once the neoprene gets wet it transfers cold so plastic bag was still needed on the cold days.
