Just my 2cp.
Twinning it was exactly what I was planning to do. I picked arcane thesis because I couldn't figure out any other way to get a twinned GAF down to a 9th level spell slot. But if there's a better way, I'm open to it. How can I do it for free? I know incantatrix will give me free metamagic twice daily, but I think that's capped at virtual 9th level spells. Residual will twin it for me every other round, but only if I can successfully twin it in the previous round on my own. Greater metamagic rod of twin spell is an option, but costs a godawful amount of gold that I was hoping to put into a cloak of displacement and boots of teleportation and a crystal ball.
