Freespool on the TDS can be.... very free, or not very free in my experience.
When I first installed it, it was hardly worth using freespool as it was not the one fingered job that David likes to demonstrate it is, it was a full on pull with one arm. After a few uses and removal and refits it was a lot lot better.
Then.... I was trying a bit too hard to get up a mud bank, which the winch bumper was smacking into a bit, the next time I went to use the winch I fell over it was so free... not sure what I did but it seems the mount is very important to these winches.
I have since serviced the winch and replaced the rather sticky grease with a much lighter one, with PTFE in it to help the freespool further, haven't tried it yet, but seems to move OK by hand
As for speed, it's about the fastest lowline around IIRC, especially if kitted with a Bowmotor 1/2.
