?'s re: Coiltek coils for NOX

I'm considering the purchase of either the 10x5 (I use this size on my G2+ and really like it) or 14x9 Coiltek coils for use on my EQ 800.
Has anyone here been able to have spent enough time with either one of these to provide
some feedback? Here in Canada they run $400 apiece so they become a very serious expense (for myself anyway). Are they worth it?

cheers...

Get the 5x10. It's impressive.

I would like to have the 9x14 but the weight is 75% heavier than the 11" coil. Don't get it. I wish they had just made this a light coil. From what I hear it goes deep.
