Test drive went great! Shifting was a bit smoother with the new GL-1 in the transmission.

I appreciate ALL of your inputs. Brad Artigue: since owning the Spider in 2008 I have always used a hesitation between shifts, especially 1-2 upshift! I suspect that syncro takes the worst beating. Also never rest hand on the shifter, was taught in a SCCA drivers school back in the 80's to use thumb and two fingers on the "sides" of the shift knob for all shifts. It was explained if there is a mis-shift, the knob will slip through the grasp. If a "man hand" of "base ball" grip is used, more damage is delivered to the transmission.

So, the glimmer of the tiny specks of brass, (smaller than grains of sand) on the drain plug are not normal? Just wondering. I figure there is about 20,000 miles in 10 or so years on this oil.

They're normal. Everything wears a bit - those brass rings are amazingly durable given how much of a pounding they take even with mild shifting.
