Vanguard pro B49 are the ones I have been using lately. I also have used the trigger sticks but the Vanguard are easies to pack. I thick you can check them out on Amazon
Bog cld-2 gets my vote. I used mine on my elk hunt this year and made a 200 yd shot on a moving cow elk easy as could be. it also gets a ton of use at matches such as Raton sporting rifle and Del Norte monthly matches.
