I'm also in the process of ordering a new enclosure for my 228 so rather than start a new subject I have a few related questions.
Seems like every canvas shop has a different opinion on what to do with that front window, flexible U, no window, rigid fold in. I'm in the mid Atlantic region so I think I need that front window to open for ventilation. Several shops have recommended not putting a U in front because it will leak and obstruct visibility, is this a major issue? They recommend adding the U later if needed but once it's there it's there.
I'm only 5'8" so under normal conditions I mainly look through the windshield the especially if it's wet with the wiper on.
I don't have an electronics box so right now I'm leaning toward .040 Strataglass with a smiley U center I can fold in to the ceiling, U's on both sides, and 3 panel roll up / removable back. Are there any other alternatives for the front I should consider?
