Haha, cheers m8! I was in Do Sports the other day and the owner told me that 80% of the people coming in for Abus want a right-handed version. I'm a righty by nature (though I shoot a puck left) and have found that's my rod hand; that's where you need more of your strength and control, so why would you reel with it? My father picked up a 6500 ten years back and I've been using it here and there but it's always taken a bit of enjoyment out of the day for me.
I think the left-handed/right-handed thing comes down to who started you in fishing.
Old school BC fishermen always crank with their right hands -I think Islanders only came in right-hand version early on.
So, if you learned from an old guy, you probably reel with your right hand even if it could have been more comfortable the other way.
It makes even less sense when you are fly fishing since you have to switch hands when you hook a fish but that's the way it is.
I noticed most American and central Canada fishermen reel with their left hand.
