= Lv 5 spell making it not low level and not a target for Low-Level effects (at least short of epic levels). Now Practical (or is it Practiced) Metamagic on one of these would get it to Lv 4 and that gets broken, especially with Speed III which would let you cast it 3 times a round (move, move, swift). Even so you'd need a practiced metamagic (or metamagic school focus) feat for each time you unloaded like that. Or another source of a generic metamagic reducer. Unfortunately they do have the feats to do it.

Then again in lesser metamagic there is a note that the reduction can't be greater than the original spell level before metamagic (might be new I don't remember seeing it earlier). Which removes minimize spell and reduces it to weaken spell and requires two uses of above feat per use. At this point, though, it's not the lesser metamagic which is a problem but Speed II and Speed III.
Arcane Thesis lowers minimize to a -3... it lowers all metamagic down, not just the +s. Badly worded, but by RAW, it happens. But by editing the requirements for how much lesser metamagic you can put on the spell, it's slightly more balanced (You can still weaken it and cast it as a twinned speed III fell drained Magic Missile, though).
