Replying to AT boots

Hey,

So my weight fluctuates between 165-175lbs and I’m currently touring on the 2019 JJ’s with the tyrolia aaadrenaline 16’s riding British Columbia backcountry/whistler in bounds . I’m looking to slowly move towards a tech set up but first move would be boots. Does anyone know if there is a 120+ flex with 100mm last that have tech inserts but fit in frames until I can upgrade binders? Kinda like the ascendants? The reason for this is my current problem is the flex on my boots.... so driving the new stiffer JJ’s properly is shit without the boots folding over.... so right now it’s a flex problem but I’d like to solve my future tech problem at the same time.

Thanks
