The bottom bait and snowman rigs rigs were identical, only the pop-up rigs were shorter. The rigs were like the pictured combi-rig, or coated braid.
I could actually swap a bottom bait rig to a snowman rig. I don't know if you have seen my sliding ring rig? A sliding ring on the hookshank, with the hair tied to the ring, so I could tie on the hair and use the same rig for either. It gave me the option of changing hair length as well to suit my 'rules' about where I was hooking fish:
If I am hooking fish hooked dead centre of the bottom lip the hair and rig length is right.If I am hooking fish at the back of the mouth, the hair and rig is too long.If I am losing fish to hookpulls, nothing on after indication of a run, or hooking right at the very front of the lip, then the hair and rig is too short.
Everything was hooked perfectly. My lost fish (on pop-ups) were actually down to hooklink snapping after being chafed on blocks on the bottom.
Looking at that, I have not changed my rigs for over 12 years, what worked then, still works now.
Its weird.
I basically had a rod on each at all times as I never knew which one would produce at any session, until by the bridge I stopped, after 3 sessions, fishing snowman rigs as it didn't produce and fished only bottom baits and the pop-up. It was also the spot where I could bait up by hand directly over my hookbaits, tipping my bait off the bridge.
The other locations were Spomb loaded, plus the stringer attached to the hook.
In any session, it was only one rod that produced, with one exception by the bridge where I lost a fish on the pop-up and landed 3 on the bottom baits.
