To walk a spook type bait or frog you don't need vertical space. Well... to set the hook of course, but, to walk effectively you keep your rod tip down. My first recommendation is to learn how to walk a spook type bait. It's easier. Take your time and find a rhythmic cadence. Keep the rod tip down and tap towards the water gently. Give the bait just enough slack to allow it to move side to side. It's all in the wrist. Once you get the spook down, to walk a frog take 75%-85% off the cadence, especially if you are using braid. It will take some time, but if you stick to it you will be able to effectively fish both style baits quite easily. Good luck.
