Has anyone noticed how large the blind spot is on the 991 cab? What is the preferred way of dealing with this? (other than driving all the time with the top down )
yes!

not applicable to the cabriolet top up

its really bad in the cab with the top up ... even with the mirror adjusted there is still a 50+ degree blindspot where a car would be if you tried to

No blind spot. This has been true for any number of cars that I have owned and should be true for 991 cabriolets as well.
Of course, you could, instead of adjusting your current mirrors, drill vertical holes through the tops of the forward portions of your front fenders and install a set of vintage fender-mounted parabolic Desmo Boomerang Wing Mirrors, as I did on my long-lost Austin Healey 3000. They are still available on E-Bay and elsewhere. You see them clearly through the front windshield, leaving absolutely no chance of a blind spot.
that's fine for a coupe etc - does not solve for a cabriolet with the top up
I'll have to try this with a cabrio, but don't see how it wouldn't work. The system depends on seeing via the mirrors, so the size of the "C pillar" should be irrelevant. You don't have to see through the wide sail panel. Maybe the mirrors are just too small.

to be clear the root of the blindspot is:
a) the size of the "c" pillar
b) the small rear 1/4-light window
c) the passenger headrest
d) the small rear window
adjusting the rearview mirror does not help, due to (a) & (d), you *can*
obviously adjust the passenger side door mirror such that *all* it covers
is the "blindspot" but in order to do that you have to adjust it such that
it provides no other coverage than that.
I currently have my my mirror set such that I can *only just* see the exterme
edge of the cars "hips" and even then it does not do a very good job of
covering the blindspot, and it effectively provides no useful coverage elsewhere
in order to safely check the spot you actually have to lean fwd and over to
the right in order to check it via the mirrors, there is no other way to fully
check it, just looking over your shoulder is a big fail, and even with my
mirror adjusted as it is, there is still a dangerous spot left uncovered.
In my case, its worth the 400 for thes aspherical mirror
installed my new passenger side mirror yesterday, very easy install took less than 5 minutes - I will update with my experience driving with it over the next
couple of days...
My first impressions are mixed; while the new mirror does "reduce" the blindspot (with the top up) it does not totally eliminate it (particularly for cars that "overlap", in the space that if you moved right you would collide with)
overall its an improvement, but not a complete solution.

I was hoping that was NOT going to be the case. Oh well, the quest continues. Thanks Larry for the effort and the update.

It *does* improve things; but the blind spot that concerns me most is where
there is a car literally just behind the passenger's door, its hidden by the
passenger seat headrest (and any passenger) and the huge 'C" pillar and
smaller rear window...
if I sacrificed a little of the view rearwards I might be able to eliminate this
spot with the new mirror...
I should have done a before/after photo of the view, but perhaps if I take an
after picture I can illustrate the field of view... (as I dont want to uninstall and
reinstall the mirrors...)
