I've been shooting a 682 gold E X trap gun like Kenny's for around 3 years. As I recall in the available info at the time the the E X with the high rib was designed for the ATA style of trap, and the low rib E was for international, though I thought I saw a picture of Al-Maktoum holding the E X version after he won the gold. I find it a bit thick in the wrist too but I got used to it. No worries about having to sleep on the couch. My wife bought it for me for Christmas.
I wish my wife would do that. All this talk only makes me want one more
