Naj will probably have some serious recommendations, mine would be practice buttock clenching so you don't have to carry the clicker in your hand

More seriously, it's not the clicker size that you should be concerned with, ( Size doesn't matter , or so I'm told

) it's in how to properly use it. If your feeling cluttered with all the stuff, chances are your not using everything as you should. Watch a good clicker trainer how they hold, and use everything and make it look simple and flowing, and practice until it becomes natural so you don't have to think about the technique and can concentrate on the training of the dog.
( Like Tennyson, I use my voice as the marker and not a clicker, because I'm just a simple man and can't multitask. Plus I have HPRs so my buttocks are permanently clenched.
