If you're the type of person that gets cold in a 30* bag at 40 then I say go for the 20* 3/4 length and use a sit pad made of CCF for your feet. If on the other hand you are toasty warm in a 40* bag in 20* temps then the 40* 3/4 should be plenty warm for you, but again use a CCF pad under your feet.
And yes I believe Adam is willing to add cuben to his quilts.
*Heaven best have trees, because I plan to lounge for eternity.
Good judgement is the result of experience and experience the result of bad judgement. - Mark Twain
