Note that the "ant swivel" you hear mentioned is VERY tiny. A normal size swivel is thrown in for comparison. Also note that in trout streams, or in tiny steelhead waters, you can get teeny and stealthy with really dinky floats and light lines. (For example: I am planning on doing some trout fishing out west with shorter rod, lighter lines, and a "miniaturized" rig.) The floats with the gram weight printed on them are drennans. For floats that are rigged with surgical tubing, the setup is obvious. Other floats, like the one below, are designed as slip floats. No worry. just slip your line thru and peg it in place with a toothpick, as shown. Drennans are expensive, but in clear waters that clear float can be an advantage......p.s. thanks to Eggsniffer for finally getting me off my duff and showing me how to post pics...that was LONG overdue!
