I'm the same way in the summertime, very fast, or I will slow it down with very hard twitches too. When i do the hard twitches, I think of the song Duke Duke, Duke, Duke of Earl, Duke Duke...Ha Ha but it works for me. Zipstick is the master of the late fall 50-55 degree topwater cadence. I've been amazed by him ( and I know you have too) on how cold of water temps that he is able to still get a topwater bite. He slows down and even stops completely.
