good method?

[geffski]

ok chaps time to wrack your brains again!
had i bit of a prob with my method mix last time out
consisted of crushed hemp,tin of tuna in oil, 5mm and a hand full of 8 mm
halibuts, bread crumb, mixed with swim stim method mix, splash of
lake water. seem to work once it was out ther, only problem being few times it broke up in the cast scattering bait all over the swim! (not ideal) can anyone recomend a good mix along the lines of what ive been doing (somthing fishy) that i can form thos big cannon balls you see the guys in the mags using.
also can anyone rocomend a good inline feeder, somthing that i can
fish semi fixed on some lead core to create a bolt effect
or recomend a good rig for this, as the swivel feeders i put on
safty clips gave me a problem with tangles
p,s im fishing the method (obviously) but also attaching a golf ball size pva
bag to the hook to hopfully create a tight patch in the soup the feeder has just created.
cheers for any help lads!
