I have the Katana and a Wimberley WH200(don't ask why) and the Katana is excellent if you need a sturdy mount and it's built like it would handle a .50 cal sniper rifle. It is very heavy compared to the Wimberley so be sure the tripod is up to the task of a 5lb gimbal in addition to gear weight. I have mine on a Really Right Stuff 34L and a RRS leveling base. The lock controls are easy to use and work great. Once balanced it stays where it's put.
It is bulky and doesn't travel as easily as lighter gimbals but I would certainly recommend it.
