It's the usage of the phrase -any time- that I was finding compelling. For both Great Reflection and Infinite Deflection, the phrase "any time" means just what it says. Not limited by times per round and so on, but any time.
However, if that's your ruling, I'll accept it. It does make Exceptional Reflection rather...overpriced.
As for Spell Turning...it's true that it is not explicitly barred from affecting "ranged touch" spells as a category, however, all the ranged touch spells I can find have Effects...and those ARE specifically barred from being affected by Spell Turning. I print an example:
Scorching Ray
Evocation [Fire]
Level: Sor/Wiz 2
Components: V, S
Casting Time: 1 standard action
Range: Close (25 ft. + 5 ft./2 levels)
Effect: One or more rays
Duration: Instantaneous
Saving Throw: None
Spell Resistance: Yes
Boldface is from me. Thus, Scorching Ray would not be subject to Spell Turning. Moving on to another example...
Disintegrate
Transmutation
Level: Destruction 7, Sor/Wiz 6
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Effect: Ray
Duration: Instantaneous
Saving Throw: Fortitude partial (object)
Spell Resistance: Yes
You see where I'm going with this. Although there could, in theory, be a spell that uses a ranged touch and is not an "effect," in practice, there aren't any such spells in the SRD that a relatively quick read through the Sorceror/Wizard spell list could reveal to me.
Anyway, I'll make some tweaks. Perhaps a wand of Ray Deflection, from Spell Compendium...as an interim solution at least...
