Philospher,
It would appear, and mind you this is pure conjecture since we don't have a final product yet, that the Cal Mini plate has more drainage holes than the skid row plate. But also let me remind you that I am not saying that one is any better than the other, I am just looking at it from what I off-road in. The more drain holes the better for me since all I get to play in most of the time is mud. Again, this is based on my personal experience and is nothing more than my personal opinion. Don't take it to heart or anything. I just look for who offers what I feel I need for my application. And we all know what they say about opinions...!
