I've caught a lot of fish on thingamabobbers. They are good for straight forward trout water drifts in water that is 2-6ft deep. I have been searching for a better alternative for a long time. I've tried the yarn indicators, but they face some of the same problems as a thingamabobber. The biggest issue I have is that the thingamabobbers don't indicate whether the flies are fishing properly. Meaning, with a vertical bobber like a balsa float, I can see when the flies are in the prime position because the indicator is pointing straight up and down. Also, with a vertical indicator, I can see bottom ticks and sideways strikes much clearer. They are much more sensitive. I've actually been using some balsa floats on my fly line - especially when the run I'm fishing is deeper than 5 ft. The bummer is that they're bulky and it looks stupid. Has anyone found something that works better than the thingabobbers? Something that shows a vertical indication of how the flies are moving? Also of note - I tried the new screw on bobbers. The balloon versions are near worthless. The trapped air plastic ones are an improvement over the thingas, but there's no difference in terms of how they perform from thingas.
