Is anyone putting with a side hinge in or is everyone hinging from the 
front?<<

Are you going to wear a parachute every time you fly?  I doubt it.  I 
couldn't wear a parachute in N891JF if my life depended on it (and I 
don't think it does).  Keep in mind that inflight structural or control 
failures in these planes are VERY rare.  You'd do far better to 
concentrate on how to get the plane on the ground safely, or at least 
under control, rather than trying to bail out.

Consider that if you take off with one latch disconnected (or even both) 
the forward hinging canopy will almost close itself...it'll hover maybe 
an inch over the longeron at the rear, but it will be in equilibrium and 
stay more or less closed.  if you take off with a side hinged canopy 
unlatched, it will likely slam open, killing lift on the right wing, and 
stall, if on takeoff.  This is basically  what happened to Allen Buzza 
in Australia.  Fortunately he survived and went on the rebuild the 
plane, and is working to finish another.

I almost lost the side-hinged canopy on N891JF the first time I started 
the engine and didn't have it latched.  That's when I decided to make it 
front hinged.

Just some food for thought.  I could go on, but it's past my bedtime...
