Well yesterday I received the new RDL seat that was custom made for me. Installed it and rode to work this morning, about a 30 minute ride.
Besides almost being run over by a car switching lanes not seeing me or using a turn signal to indicate the switch which puckered me up the seat felt pretty comfortable.
It does set me up higher but gives more support to the under side.
I do have a longer reach to the bars, my arms are extended more and that is a concern.
Not sure if I'm sitting back further or the reach is further because I'm sitting higher or a bit of both.
I'll give it the break in period before I judge.
