Robert, take it to someone who understands resonators and carefully explain your playing style. Like you and all the folks here, most guitars techs don't know what to do with one of these and setting them up involves different things than a normal acoustic.
It doesn't matter whether you use a one or two piece saddle - they both have advantages. Two piece is much easier to tension the cone but its harder to get the correct string height.
I don't see how a one piece saddle could be used without blocking the spider/cone tension screw.
BTW: (3 years later, sorry) Your photobucket images can't be zoomed.
