Agree with Brad. I am not aware of anyone who makes noseleg struts, everyone uses a main leg strut with a spring rate and pre-tension suited to the weight put on a main leg. The result is a noseleg with a higher frequency than the main legs, often so hard as to have no give at all, and the result is a bouncing nose while the main legs are going downwards, which pitches the plane back up again. I have altered the springs in all of mine and it makes a difference.
