There are a few recent threads on winches which should answer your questions. It seems to me that you are almost as likely to screw your H2 up with the 9000 as you are with the 9500. My rationale for the ti is that it provides you with feedback on the heat of the motor while in use. Motor heat will give you an indication of how hard you are working the winch which is related to the force you are applying. More importantly it should prevent you from burning out the motor on the winch. I am not an expert in winches(nor do I play one on TV), I have however burned out many electrical motors, similiar to winch motors, on other machinery. I would rather pay $100 or so more now, to protect myself from turning my $800+ investment into garbage because I overworked it.
