I'm starting up a new fantasy league on the premise of using mostly team-independent statistics and weighting so that a replacement-level player is worth 0.  The separations between events like singles and doubles are taken from linear weights, but the baseline values have been adjusted to achieve the eponymous replacement level neutrality.  It is a total points league (meaning everything gets added together, as opposed to category-based scoring).  Points are scaled as runs (in essence I've tried to reverse engineer VORP, although the positional adjustments aren't there; 2Bs and SSs get a DP bonus, at least). I'd like it to be fairly deep, so there are large rosters.  

This is a Yahoo league; direct link: http://baseball.fantasysports.yahoo.com/b1/register/tos?league_id=78859&password=yaybaseball

I've also thrown in a few "fun" bonus categories like no hitters and grand slams.
