Bar Ends: Flush or slightly inset?

I think I've figured out how wide I want my bars and right now there's about
1.5" of bar sticking out from each bar end.

I'm going to trim the bars with a pipe cutter. Should I leave, say, 1/4"
sticking out past the bar ends or cut them flush?

I guess this is an engineering question about the collapsability of the bar
tubing under the load of pulling on the bar ends when climbing.
