When I had my Toyo field the only one movement I thought was kind of difficult was the front shift. It was very difficult to shift the front standard. Was there something I was missing, a lever or something that needed to disengaged that would have made the shift feature take less strength to actually utilize. Also what is this shift mechanism like on a Horseman field? One more thing can the Horseman's focus be locked without applying negative force to the opposing focus knob? Thanks in advance.
