you should ask yourself the major question first!
how much do you want to spend on just a helmet?
there is a major price difference between TE and AP!
i don´t know about the TM helmet, but don´t hesitate and ask him!
my personal favorite is the TE2 (because of its screenused origin) followed by TM (last pictures posted here are looking absolutly great) and last the AP (at least when not thinking about money)
Last i talked to TM his price for a finished helmet was Great about the same price you would pay for a TE2 helmet kit. I would go with TM
far sharper pulls then TE2, and it;s about ready just add stickers or paint!
but if you want to put together your own helmet then go with TE2 but if you havent put together many TE helmets you might mess up a few times
