I thought the Hobym mounts we're pretty flash, very light weight for the carrying capacity. I have no experience with them and they did start with a few teething problems which seem to have been resolved.
The traveller version weighs in at 3 kilos and can carry 7-13 kilos, the upper end of the carrying spec's need a counter weight.
The CRUX T-4000 does not require counter weights up to 40 to 60 kg...
