I have a JD2320 that I just put a Piranaha tooth bar on. This is a 200CX FEL and I used it for the first time a couple days ago. It is really dry and the ground very hard here. I had 2 dirt piles to move that were made when it was almost mud. The Piranaha cut into it without any problems. Good bucket full of hard mud dried dirt. Began clearing Honeysuckle that has grown over several acres and small saplings everywhere. The Piranaha tooth bar is super at taking the Honeysuckle, vines and all other trash right off at the base with little effort. I am impressed with this tooth bar so far and I would recommend it for the work that I have to do. I bought my tooth bar from BXpanded and it came UPS in a couple days. Shipping was 39 pounds and this is a 49 1/2 inch bar. I think this tooth bar is a must have item and I am happy with it, good luck whatever you decide.
