Proper positioning for barend shifters?

[RFC]

I am rebuilding and outfitting a 1998 Scott Tri bike. When installing the barend shifters at the ends of the aerobars, how should they be positioned -- i.e., low pushing forward to high or high to low -- from the perspective of the rider?

Thanks

Normally pushing down for higher gears (small chainring/sprockets)

If they're Shimano, they are positioned however you like them. Some have them pointing "up", (harder gear towards you), some point away(harders gear down).

Smaller rings on the back are harder, and smaller rings on the front are easier, so I don't think it would "up=harder" or whatever. I'm pretty sure it would be "up=smaller ring, down=bigger ring" or vice-versa. Anyways, that's how down tube shifters are.

With Shimano bar ends, you can mount them how you want. This changes the way the cable is pulled.

Like this would be pull the shifter towards you for an easier(bigger) cog and push it down for an harder/smaller cog. The fron shifter would be pull it up to go to the big ring and push it down for the small ring. Which is the way I would say most people mount them.

This is the opposite mounting way, or the shifters pointing "up".

For years I raced with the bar end levers fitted to my Vision Tech integrated Trimax bars facing up, but have recently moved to another frame and during the transfer and rebuild swapped them to facing down (like http://www.tritechmultisport.com/EBA...nch/DA54cr.jpg ).

They now sit more level than upright as before so there should be a slight aero advantage...
