Unmodified?

[SigilWraith]

I apologize if this has been asked and answered ad nauseum, but I had a quick, QUICK question about spell resistance, and a forum search mainly turned up some sort of 7 page argument about a white dragon. I have no intention of opening THAT can of worms again holy cow! My question is a bit simpler in nature, although two-fold:

A) From what I'm reading in the PHB, the roll to overcome spell resistance seems to be an unmodified d20 roll... is this correct? If it is eventually described as being a modified roll somewhere in the rules, I seem to be overlooking it.

B) Does anyone here house rule SR to make it modified by either caster level or attribute modifier (according to the caster class' prime attribute), or would this just be a bad idea for some reason that I'm not taking into account?

Originally it was modified by attribute bonus, but it was soon changed to unmodified. The few times it has come up in my games I have been happy with the unmodified results.

[SigilWraith]

Ah, so the burden of fate-dodging rests solely upon the target creature's resiliency and aptitude to resist... works for me!

Thanks for the prompt reply

I have always seen it as an unmodified roll.

I have never had complaints from pc's or other CK's.

I think only the first printing has wording for it to be modified. It wasn't supposed to even say it then, so was removed in a later printing. I'd have to check to be sure it was the second printing that it got removed.
