Good choices all
I use the rubber hose for mine (courtesy Jay Pratt) and it has worked fine for 11 years. Until you mentioned it, I had forgotten it was even there.
I also use the Mike Zeller latch. Mike sold me one at my first RV-8 Oshkosh 11 years ago and its foolproof. Glad to see you can now get them @flyboyaccessories.com.
The McMaster Carr latch is also popular and I have several friends that use it and like it.
Lots of good choices for you.
