Thanks for all the replies and COT 320 sounds like a the way to go and others have mentioned it to me in person.  
One supplier had suggested doing a pre-coat of distilled water and once the paper no longer had a sheen, then apply the sensitizer.  Too crazy even for platinum.  
I haven't checked the prices of COT 320 but wasting a day or 2 trying to make some other paper work is much more expensive as BOB pointed out, not to mention the years shaved off our lives from the frustration!
I've had years of successful printing w/Platine but that seems to no longer be the case.

       At the cost of the PT & PD salts I hardly ever use anything other
than COT 320.  Even with cyanotype, I have commercial work pressures so,
when I print cyano where the chems are cheap, my time is more valuable than
the difference in cost between COT 320 and cheaper papers.  I am not saying
that one shouldn’t use other papers that have different qualities (surface
texture, color, thickness, translucence, etc) I am just saying that I use
what works best and keeps me from having to redo things.

Can't really add anything to the comments existing. I was stung with two
different batches of crap Platine about five years ago so lesson learned.

Ah, probably no.

I pounded (and wasted time) with old and new cyanotype and Platine
and was plagued with mottling...

I assumed "Good for Platinum, good for Cyanotype."

I did not try Pt/Pd, but I suspect I was seeing something similar
(similar "siderotype" process).


P.S. Unfortunately I was not undercharged...
