Hey S'mon! 
I think the thing about the official Challenge Rating system is that its just about works well enough over the first 20 levels (or at least the first 15 or so) to not be much of a problem. Its really when you get to epic levels that you can notice major discrepancies, and as you know the CR/EL system I designed was initially created out of problems I saw in trying to use the official rules to balance epic/immortal gaming.
So although my rules are clearly superior, unless your PCs are either very high (15+), epic or immortal level its probably not a necessity.
Of course its still worthwhile taking a look at the pdf even if you don't plan on using the challenge rating system presented, because there are (IMO) some good ideas on balancing monster design, class/prestige class creation and so forth.

S'mon said:Re CRs, as a GM who usually runs published scenarios and doesn't have time to go over all the stat blocks I'm of the opinion that, to coin a phrase, you go to the table with the CRs you have, not the CRs you would wish to have. It might be nice to convert to the U_K system but it requires several extra steps in XP calculation and for now I'm sticking with XP based off CR. WoTC CRs are far from perfect, but they appear to do 1 thing quite well, which is provide a monster that is a challenging encounter for a PC group of level equal to the CR.
