i hope they use the 4r36,
only way i could see them using the 6r15 is if they decided to bump them up to "prospex"...
though i guess the monsters kept the same 4r36...
and yet they also have those new monsters with the 6r15...
gets confusing trying to figure out what they are planning.
Either way, personally i vastly prefer the SKX173 to the 007...
i just prefer the seconds hand and the "Aztec-Style" markers.
Some of this might stem from the fact that the first time i showed my wife my 009,
she asked me "why would someone use markers that look like tampons?"
