I'm loving my new Green Machines (light, torsional stiffness, climbing comfort) but I’m missing the smooth, progressive flex of my Flexons.

I swapped the tongue out for a Flexon last night, flexed them in my living room and didn't notice too much difference in the flex. The Flexon tongue doesn't really 'sit right' in the boot either; this may affect its performance??

Has anyone swapped out for a flexon tongue? Has it made a noticeable difference when skiing?
