you just set up with stardard semi-fixed legering gear, i prefer inlines, as it keeps the centre of gravity on the line. To stop the lead from swinging everywhere whilst landing a fish, but safety-clip gear will be fine too. i prefer using 1oz - 2oz leads for thins, as it'll make landing fish easier.
from the lead instead of a standard hooklength you tie one from around 1ft upto to 12ft. A good starting point is half the depth of water you're fishing in. And then the hookbait will be halfway between the lakebed and surface. i use 10lb drennan double strength for this. But any line between 8-10lbs will be fine. Thicker lines will weight down the pop-up, and lighter ones you will risk being snapped, unless the fish you're going for are not too big (upto 10lbs)
You tie this rig just incorporating a knotless knot, just with more line.
On the hair rig you put on a floating bait, i prefer tutti pop-ups, but anything which will stay on the hook for a while is fine, fake baits etc.
When casting with a long hooklength, say 6ft or more, i is better to place the hookbait into a cup whilst casting, and have the line between the rod tip and hook. so it wont hook anything as easy when you cast out
hope it helps matey
tight lines
