I'm finally ridding the fiver of the Marabombs ... for those of you that have gone with the nitrogen fill ... over several months, does the pressure stay pretty near the same or do you find the need to have them topped off a few pounds like tires with just air in them? If they tend to bleed off over a period of months similar to plain air, I feel that pretty much kills any advertised advantage. I won't be carrying a personal nitrogen bottle around and nitrogen fills in my neck of the woods are few and far between.
