Because it's very hard to be a heavy hitter without accruing lots of PIMs, I think a very slight alteration could be beneficial to the VFHL. I don't think, however that someone who gets 200 hits with 200 PIMS should be getting many more fantasy points than someone who gets 100 hits but only 50 PIMS. Perhaps look into a ratio?
Or do what I dream about: look at the ratio between HITS and HITS TAKEN and do the hitting points based off that.
