Ask my missus...I don't remember....
Seriously though, like most people these days (I think?) I hair rig it. Obviously, those into rolling don't, and they bury the hook. I am not 100% convinced that the shape, or whether it is 'ragged up' or not makes any difference. I think the fish are far less bothered about shape/ragged edges than anglers, but it won't do any harm to do it if it gives you confidence . Most of the successful meat fishers I know use it straight out of the tin, cut to a convenient size/shape with a knife. I prefer to use a rectangle cut from the corner of the tin, so that an end and a side have the tougher outer skin, so that the stop doesn't pull through so easily. Simple, but works for me.
Some also prefer to chop the meat and fry the pieces in various spices, curry or whatever. Again, this toughens the skin, and is repute to be a good change bait for when the standard stuff 'blows'. Again, not something I have dabbled in yet, although an angler I have a great deal of respect for does something of the sort, if/when he uses meat on the Loddon I think, so I may giver it a go for that reason alone.
Thousands of options, and preparing the latest surefire winner gives us something to do to keep our hopes up, if nothing else...and it beats the hell out of decorating
Cheers, Dave.
