I have the king cobra, havent used any other clutches, but its really not that expensive, id go ahead and upgrade and not have to worry about a clutch for a while. Mine grabs awesome, pedal effort isnt bad, if your leg is sore or something it can be a pain, but I dont worry about it. It grabs hard and has has held up great for like a year now. Ill be running my 12 second run soon and my clutch isnt even on my mind.
