Great Question! The best action is the one the fish prefer at any given time! So, the Marabou gives "more action" and the Rabbit hair gives "less". Sometimes, like the old saying goes..... "less is more" ! Personally, i think that there is a time and place for both. Early in the season, that extra flair action from that marabou will attract more hits. The more subtle, but flashy action of the Bunny Butt - Rabbit Hair- will pick off the bigger, more wary fish though.
