yes you are right there Lars, only the rotor and spool is bigger on the TP10000fc, If you are going to get a twinpower the 10000 is the go as it can hold more line, and is marginly lighter. I have a 10000fc myself and have tangled with a 30kg plus fish on it and it just doesnt have enough power or drag to get the fish in, not saying you cant do it, its definately possible it will just be hard. It doesnt have much drag for the size of the reel, Only about 7kg. When popping the handle has a tendancy to come loose. I would personally opt for the catalina 4500h.
