Hi Tony,
Not off topic at all. A couple of observations:
I am only aware of some early Simplicities being available on double crocodile (well, alligator, as you point out) and it always seemed like the ultimate luxury to me.
Journe straps have always been very supple, and while the addition of a second crocodile layer does decrease this somewhat, these straps are still thinner and more flexible than anything I have new from Breguet, JLC or ABP.
I would expect that the inner crocodile layer should wear quite well, but I will have to report back on that in a few years!
Interest if anyone else has experience with double croco straps ...
Regards
Andrew
