Jim answered a couple similar questions to this on the TT Score product page. If memory serves, you should have enough parallel section to tip trim each club to length. This should obviously make it stiffer than IR11 with no issues. However, I’m pretty sure that would still get you no where close to X flex.
You’d have to trim these shafts at least 1.5” maybe more to get them to play X flex. Of course, doing that wouldn’t leave you with enough shaft to get them to a reasonably playable length.
