Sorry to keep bothering you guys. This all seems like sound advice, and I appreciate it.
OTOH I'm more confused than when I started. The correlation between body weight, flex (which I understand to be forward flex) and lateral response seems weirdly hard to pin down. Our resident boot specialist JB likes the Falcon, but recommends soft race boots (Atomic RT100 or 130) as alternatives. So I guess a 130 is soft enough for me. Except when it's not; Atomic says its 130's are very stiff. Then again, JB seems to like soft race boots for everyone...
Meanwhile Atomic lists the RT TI100/CS100 as soft racers, both apparently plugs (wrong here?), but with flexes of 100?!? Yet my Falcons (and my old beat up XWaves) are 110, even though they're not plugs and not considered race boots. In fact the XWaves are considered great bump and powder boots. Meanwhile there are a slew of race models listed here by D(C) which all appear to have flexes of 100 except for the 150!?!? Lange. Which a number of people claim is actually fairly flexy
So I'm missing something terribly obvious. Am I correct or way off base in assuming that:
1) Appropriate flex for a race boot, like a rec boot, is really about body weight and venue/type of sking, so it's the lateral stiffness/quickness of a plug, not the flex, that really differs from a rec boot.
2) You really can't compare flexes across boot brands.
3) Therefore, a 130 flex for a lightish male like myself would be inappropriate in some brands, fine in others. Which is OK, since there are plugs, which Barrettscv thinks are desirable, that apparently are softer than my Falcons. Except that maybe there aren't; TakeControl thinks I won't be able to flex a plug, which implies they're all a lot stiffer than my Falcons.
4) Or maybe I'm wrong from the getgo, and the more aggressive you get, the stiffer the forward flex you'll want, like the progression from a nice comfy XWave 8 to the Falcon; force as a product of mass and acceleration. But if that's true, and even light racers need 130's and higher because they go so fast, then why are there all these 100 flex race plugs in male sizes? For pilgrims like me? Or for racers who like to bend their boots into pretzels in a turn? Or for strangely tight flat SL's where you just can't go over 15 mph?
4) This gives me a headache
