What to do if the canopy opens during flight ?

I have exactly the same concern about those tilt forward canopies; and don't
know how, or if, it is adiquately adressed. It just seems like a high price
to make egress easier on the ramp.

In my experience, a conopy does nothing to make egress easier on the ramp.
In fact, I recently stopped renting a factory made Zenith partially because it
is difficult for a solo pilot to close and properly latch the ill-fitting
canopy. I will take a real door any day.

The canopy on a Grumman does what a canopy is supposed to do and slides
back.

What a canopy really does is simplify airframe design, particularly for a
mid-wing design; but it does so at the expense of adding a whole new set of
problems.

The only problems with Grumman canopies is the $3 nylon bushing that
wears out and you need to clean and lube the tracks now and then.

I agree completely!

Personally, as a builder, I would be inclined to add a couple of hand grips
in the glareshield and a ridge across the floor about a foot ahead of the
seat, to make it easier to heave myself up and out; but that does not
detract in any way from the basic concept that the canopy of a small GA
aircraft should slide back as its means of opening.

On the Grummans, there is a metal bow for the seal and latching
mechanism that works fine for a hand hold.

The seat cushions flip up with your toes so you step in onto the
seat pan, then the floor and sit down. It is a lot easier than it
sounds.

That sounds like a good concept.

BTW, that paint scheme suits the tiger very well.

The folks at Zlin would disagree :-)

Only because they had a bunch of Pole illegal immigrants working in the
factory who were putting the canopies on backwards and by the time anyone
noticed, it was too late...
