Depends on what you want to do and where you want to fish mate.
Helicopter rigs for distance.
????Sliding bolt rig????
I think you have two rigs in one there smudge.
A bolt rig or semi fixed as it should be, is a rig where the lead does not move.
A sliding rig is a rig where the lead is free running on the line.
I'm a bit confused as to what you mean, so come back on with some more information mate. Some body will help you out.
