Barbs on hooks

Do you debarb the hook when fishing for steelhead? If you do do you also fish flies in tandem. When tying a fly to a fly with a debarbed hook how do you tie them together and with what knots?

Asking a lot here but everyone has been very helpful. By the way I just finished a great book = Nymph fishing rivers and streams by Rick Hafele and am about to start another by john Nagey.

steelhead can push the hook out of there mouths so wen u debarb a hook u lose more fish

but do they have opposible thumbs?

what if two steelhead worked together to pull the hook out?     ''thanks buddy i owe you one'' say a steelhead to another.

I've been fishing strictly barbless several years now for steelhead and haven't noticed any difference in the amount of hooked fish lost.  I find it easier to unhook them once landed and hooks come out of me easier too.
 
I don't usually fish tandem rigs for steelhead, but often do for trout.  The barbless hook doesn't create any issues when fishing tandem rigs.  I tie mine directly off the bend of the hook with a cinch knot.
