Hmm, if you want guys who ordinarily wouldn't have value to have value, then Holds is a great category. It opens up a whole new brand of fantasy player that is usually worthless.
As for your offensive categories, the ones I would NEVER want to use are Ks and Fld PCT. I would also never play in a league with OF assists.
To each his own though. Personally I like the OPS category in addition to batting average, rather than OBP instead of batting average, but again, that's just my opinion.
As for the categories CG and SHO. I hate these categories too. You have to keep in mind that these are fairly rare occurrences and the winner of these categories are likely only to have something like 12 and 5 respectively. Some people may not get any of these. I know I didn;t have any until the end of last year, when I finally got a couple from Dontrelle Willis. I just think they're too big a swing to include. Ditto for triples. I don't like to get too fancy. I like to stick to stats that all of your players stand a reasonable chance of adding to every time they step on the field, and CGs, SHOs, 3Bs, and OF assists aren't that.
Just my 2 cents.
