I'm going to assume, esp knowing what SaxMatt uses, that he uses a larger weight because it's easier to mold a big ball of pack bait around. This is what I use, they're long and flat and I can mold a softball-size ball of oat pack onto it as long as it's the right consistency (not too dry that it falls off and not too wet that it doesn't break down in the water). You can find 1-oz versions of these somewhere that I've used for pond fishing, but I fish only tidal rivers now so I don't go less than 2-ounces. I've never used other method feeders but lots of people do. I've just always found these easy.
