Replying to Full tilt booter flex?

sorry, i searchbarred but couldn't find quite what i was looking for.

What would be the equivalent in normal flex ratings (like 80-135) of a 2009 booter flex 2 tongue?

I'm 5'7" 145 and ski almost 100% park. The boots fit amazing for me but im just wondering if its too flexible.

I know what spk flex felt like (these boots did not fit, they were bad for my feet) would it be comparable?

Also, if i were to need to change the tongue, anyone know where i could buy one immediately in the Massachusetts/boston area, or in the stratton area, or in the okemo area?

thanks.
