Running Rig or Bolt Rig?

I used to always use a running rig but recently started using a bolt rig. I feel a little more confident with the bolt for whatever reason. How about everyone else? And if you use circle hooks or a baitfeeding reel does that influence what rig you use?

I use both with no real rhyme or reason as to why. The thing is, I feel a lot of time when I cast out a slip rig, the sinker fowls, turning it into a bolt rig anyway. At least with the way they run some times it feels that way. Seems with a bolt, an automatic hook set is more likely, Unless you're leaders really short. I don't have much specialized tackle either. I use sz 6 or 8 2x strong scud fly tying hooks for my hair rigs. Only hook other than eagle claw bait holders that have the eye turned the right way for a hair rig. At least that I've found locally.

While I'm not trying to say there's something wrong with your rig, all the reading and searching I've done always shows the hair rig tied with a hook that has the eye turned the opposite direction as a gamak octo hook or straight. I did some shopping around on some euro carp online tackle places and found more of the same.
