Replying to mounting madtrix

Alright, i've got the 02-03 Head Madtrix and p12's. I need some suggestions on where to mount the bindings. I've gone back and read all the posts relating to it and the majority seem to say about an inch(2.54cm) or 3 cms forward or the big mountain recommended mount with the bm side forward. Is this still what everyone likes? Those posts are mainly from last season. Also, if you give me a measurement, try to keep it a measurement from the factory recommended point forwards towards the tip(which will be big mountain) and not a measurement from true center back.
thanks-
