Yes, Monte Cook's AU is what I was referring to. Quite frankly Thanee, we have not had any problems. We are currently using the D&D spells (though I think we will be changing to the AU spells with the next campaign), but we have not used all of the metamagic feats. Under AU there is one feat "Modify Spell" which includes 5 or 6 feats within it (double range, double duration, silent, still, 1.5 x effect, maybe 1 or 2 others). I do not believe 'persistent' was one of them.
Keep in mind that you do not have to use a metamagic feat if it is "over the top." Contrary to popular belief, not everything in the rules is balanced correctly. If you did want to use a "stronger" feat, I suppose you could use 3 slots instead. In any case it is still easier than having to refer to any rules you may have had to come up with to determine what you need to do.
Bye for now.
