When I was Pushing jigs primarily, I Pushed with 1oz trolling weights - 2ft long leaders of 6# mono - at around 1mph.
My setup was mainly four 14' rods with line counter reels & 20# mono or 30# braid as the main lines. They could have just as easily been spooled with 10# mono, but the outfits I used were bought from a friend that could no longer fish due to health problems & was my primary mentor on Pushing jigs, so I just left them as he had them. My rod holders are the Hi-tek Elites (18" risers).
This was before I purchased Livescope, back when my main electronics was a DI unit. Once I started fishing with LS, the rod holders & Pushing equipment took a back seat to single long rods & flipping/casting. BUT, should the conditions warrant Pushing jigs, I'd use my LS to search ahead for schools of fish (& their depth) & to help avoid running over brushpiles & other cover (unless the depth of my jigs would clear them).
I try and keep my lines close to a 45deg angle when Pushing & determine the depth of the jigs by multiplying the length of line out by 0.6 (so if I have 20ft of line out below the surface, I guesstimate my jigs to be running about 12ft deep) Generally speaking, running at 1mph with 1oz weights, the lines will not quite be at 45degs ... which is fine with me, because I'd rather err on being shallower than deeper. Also, I'm sure the 20# mono & 30# braid are dragging thru the water more than 10# mono would, which could also be causing the jigs to run shallower than my estimate.
My main lines have a duo-loc clip tied on the tag end ... clipped to the trolling weight ... another duo-loc clip is put on the other end of the trolling weight ... then my leader line, which has a loop knot, is clipped onto that clip. Leader line will break before main line, so I keep a dozen or so leader lines/jigs wrapped around a 6" section of Pool Noodle for an "on the fly" change out.
Also, should I want to or have to use the Spider Rigging technique ... the same equipment could be used, with the exception of the 1oz trolling weights, which I could easily switch out to 1/4oz or 1/2oz or 3/4oz Bullet Weights (depending on rod action & wind conditions).
