Well even as Super Tails alone without the flickies, he's a tiny bit overpowered as it is - you don't really have anything to worry about other than things that smoosh you. As soon as you walk off a ledge or something you're free to fly and live to tell the tale. If you walk off a ledge or something and Tails is an AI, switch to him quickly and you're good. I personally see no real burden with the extra speed. I super agree on it being a pain to get the emeralds, though.
