Do you notice any difference in acceleration? What about RPMs?

Thanks
At 2% I think I am fine. I drive like a granny, but I have enough acceleration in the lower gears when I need it.

I do have a 5th gear mod here :

This is a 21% change in RPM, not the ~10+% you are talking about. My 5th gear is a lot weaker than it used to be. I do have to use 4th strategically, but usually not on my main commute. But this *only* effects my 5th gear. I don't have a lot of hills where I live, so it isn't something I have to deal with often. Your tire mod will effect *all* your gears.

If I were you, I would target the 5.1% or lower change in tire size.
