man, im in exactly the same boat, same injuries, time frames, setup, etc. and i agree 100%.
but what kinda brace are you talkin about? like the cheap neoprene onese with the hinges? or like a legit one? if its not a fitted brace, you really need to invest in one. the over the shelf/non fitted ones do almost nothing, while braces like astrix, Don joy, CTI etc not only dont get in the way at all, they are awesome as prevention, and keep you incredibly stable.
pretty much what im saying, is DO NOT chince out on saving your knees. if it means dropping bank, its worth every penny. my knees/ankles are fucked pretty good, and i would do just about anything for them to feel like they used to.
