Best secondary for a trapper?

What do you guys think is the best secondary for a R/x trapper and why?

It depends. If you're doing trap runs in the UW, then by far, R/Mo. Rebirth, ftw.

Pretty much in all cases otherwise (that I can think of) R/Me would be ideal because of:

Mantra of Resolve - Stance
For 30-78 seconds, you cannot be interrupted, but each time you would have been interrupted, you lose 10-5 Energy or Mantra of Resolve ends.

or mantra of concentration!

I pretty much abandoned Mantra of Resolve since our Nerf happy buddies at Arena.net ruined it. Because of that I like R/N better for Plague Touch in PvP. For PvE, and UW Monk.

PVE Monk By Far

For PVP though you have options
Martyr Trapper - Monk w/ Marty
Mantra Trapper - Mesmer w/ Mantra of Resolve
Touch Trapper - Necromancer w/ Plague touch

in PvP...

Oath Trapper - R/
Resolve Trapper - R/Me
Martyr Trapper - R/Mo
VIM Trapper - R/W
Touch Trapper - R/N
