I pulled the trigger.
I bought a Whites Fusion Sport with the SLT seals and a p-valve and a She-p.
I ordered it from DRIS and benefited from their lifetime warranty offer.
I will try chuck taylors for my feet.
For the time being I will stick with one of the many pairs of wet gloves I have or no gloves.
I am going to get some fleece undergarments.
The suit should be here in three weeks, giving me about 3 weeks to try and learn how to use it at home before Bonaire. If I get it figured out, I will dive dry in Bonaire!
Thanks, thanks, thanks you guys for ALL your thoughtful answers, direction, and comments.
Until then I will continue to freeze in my Akona 7mm (borrowed from my smallest sized son - men's small) with my 3/5 hood.
I will let you guys know how I make out floating upside down on the surface
How much weight should I try? I weigh 135. I usually dive with 8 lb with a 3mm full suit.
