Looking to replace the flex tongue in my Pro Tongue Liners with the Power tongue to add some downhill stiffness to my setup. Liners are in my Hawx Prime XTD 120 flex boots (I weigh 220lbs for reference). Does the Power Tongue add any noticeable stiffness? Would a tongue for a 1 size bigger liner work? Intuition is out of the tongues for mondo size 27 but has tongues available for mondo size 28/29.
