Hi mate,
Initially I was using a coated braid, Suffix something or another but went onto ESP Tungsten Loaded which is 20lb I believe and really good.
More recently using a doubled over piece of stiff Korda Mouthtrap Chod Filament in 25lb for the hook loop, with the Tungsten Loaded as the boom section.
Either way I want the smallest hook end loop possible, prob 1 inch absolute max so it's as low as I can get it. Tight to get the hook on once the putty has been applied.
I have used longer booms and hook end loops so it's a stiff hinge rig early season when fishing over silk weed, but the low version works well for me generally.
Hooks are 4's or 6's Korda Choddy hooks or JPrecision Advanced Chods.
You'll need to pull the hook loop through the hook eye with floss - it's a tight fit on the stiff version, but I do prefer it.
Looking to adapt it for bottom baits at the mo. 👍
