I love making my own rigs
I get great satisfaction from catching on them knowing it's all my own work
Long snoods for a calm sea and short ones for rougher water, clip down for distance or loose for a lob into the surf.
For flatties beads work well.....
Luminous ones in dark coloured water.
Red and White over clean sand.
Black and Green on mussel beds.
I avoid using floating beads as I'm never sure if my bait is on the bottom where I want it or floating around like a fairy.
My rig of choice is the one up one down as it's easy to make and you know there's a bait on the bottom as well as one flapping around just above which pretty much covers all bases for me.
A two up one down may be better but I always think it's more to get snagged.
To keep costs down I don't use crimps to hold the snoods in place just good old fashioned knots which they say can weaken your line but when using 60lb line for the main body it doesnt make that much difference surely.
I like to use memory free line (15lb to 20lb) for the snoods then it doesn't end up getting coiled like a phone cable.
As for wrapping the rigs I always use pipe laging foam cut to whatever size is required
Which ever rig you use of course depends on what your trying to catch but with sea fishing anything can happen so the two most important things of all would be top bait and sharp hooks
