First, congratulations on the variance.

I can't comment on the Yaesu rotator as I know nothing about them. I'm 
running over 200 foot of cable to a PST61 which works well.

I'd stay as far away from 9913 as possible if they still use the quasi air 
core. There are those who say all you  have to do is make sure the ends are 
properly sealed to avoid problems and I used to be one.  I had nearly a 
thousand feet of the stuff installed here for years with no problems. Then 
the old tower took a lightning hit which removed the sealant and within 15 
minutes I had water running out of one rig onto the desk. The rig survived, 
the top of the desk didn't.  I have since replaced all of the 9913 with 
LMR-400 which I am now replacing with LMR-600. Both are available for some 
reasonable prices depending on where you go. I think I paid $1.29 a foot for 
the LMR-600. Good quality crimp on connectors are available for the 600 and 
400 for about $5 USD give or take a tad.  BTW: Except for the one run the 
9913 was still good, even though some of it had been up over 15 years with 
no problems, I gave most away with the rest getting pitched. It just wasn't 
worth the risk to me.

One correction, I remember the run to the vertical on the end of the shop 
appears to be 9913 and I just happen to have that down.  It's only about a 
70' to 80' run so I may use some of the LMR-400 from the big tower I'm 
replacing with 600 rather than installing LMR-600 for such a short run even 
if it does have 6-meters at 750 watts on it. If it'd quit raining long 
enough, I'd go out and see if I can get enough without having to climb the 
big tower very far.
