probably a bit late for you Mike but I use two different methods for worms (and I'm talking about lob worms here)... when I want a very fine presentation, I cut the worm in half, then i'll push a baiting needle in to the worm (about half way along the half-section) and out of the cut end; then i'll use the baiting needle to pull a size 16 in to the cut end and then out aapprox half way along, so that half of the worm is threaded on the line and half sits below. Worked really well for me on lakes whilst float fishing, great for perch and bream but surprisingly effective for bigger roach too.
If presentation isn't the be-all-and-end-all, i'll use a size 12 or 10 hook, then cut a lob worm in half and just hook the worm on, always on the cut end. Then I cut a very small section out of a red elastic band and use that as a "keeper" pushed on and over the hookpoint to ensure they don't wriggle off. Great for big chub - and no need to hair rig, so easy to change to breadflake or paste should you so wish.
Incidentally, how did you get on?
