alreet blinky bill,nowt at all m8,never used it as not for fishing stressed out on the bank every season wary fish..where i am fishing at the mo the fish are just hard to attract which makes them seem hard to catch..but have caught on a few similiar rigs that are from the same principle..elsewhere..caught me 20`s twenty years back when 20`s where few and far between in`t NW
as to the rigs abilities..yes it should expand in width on blow out increasing its anti-eject properties and if you make one to the precise pictures using 45lb nylon coming from the shrink tube (not bristle),you`ll find another added extra..which what this rig is actually designed for..all type of feeding fish..whether confident or rig sitters..wink!!!
