Count me in also as a regular bobber guy. I like using the Wasp carlisle types as 1) I find the red w/ chartreuse stem the easiest to see 2) the long stem tip acts like a speedometer needle and it is easier for me to see what the rig is doing 3) They are cheap enough that I don't feel like I need to jump in after it if I break off like a 3 dollar bobber 4) I like the truer drift and weighting characteristics of balsa vs a foam or plastic bobber. Another one that I like are Graylings, but they are hard to find and I only use my treasured stock when fishing relatively open rivers. The clear plastic ones are becoming the rage as of late. With those, I like the Red Wing Black Bird ones as they can hold more weight than the Drennans. However, they can be hard for you, and other fishermen to see.
There are alot of good bobbers out there, and, like any tool, it is good to pick the best one for the job.
One commonality with all of them is that it critical they are properly weighted for maximum sensitivity. On a carlisle, that would be when the point at which only the top 1/4 of the body of the bobber is above water.
