This is a well written document. He states which rules or variants he does or does not use and why. His rationale is sound and makes sense. I do not plan on using every change he has, but will incorporate many of them into my campaign.

This -free- product is well written. It explains which optional rules from the game this DM uses and why and lists a few rules of his own. With some rules I agree, with some I disagree but your opinion may vary. However, this is free. You have nothing to lose by reading it.
