Hi, I have a pair of Fischer Travers CS boots, size 29.5. I'm looking to upgrade the liner because the material is too thin and I feel hot spots from the interior rivet of the BOA dial in each boot. Though in general the boot volume with the stock liner is fine for me. What size/volume Pro Tour liner would you recommend for this boot? I was also interested in the Pro Tour "Power Tongue", do you stock those? And if so would the medium volume power tongue work with the low volume liner? Thanks!
