Thanks Colin, great review.
Just to add one or two things.
1. As i am looking for a blue Strap for my Ploprof i ordered a
blue one from O7, but the color looks quite cheap IMHO
and does not fit at all to the blue of the Ploprof dial.
2. i also ordered the strap from TF in 20mm (nice price by the way)
and this one really has a strong chemical smell which i hope
will be gone when i wore it for some time.
3. i also own the original Omega strap in black this one is from
my point of view the best replacement for an original isofrane strap
Also can´t wait for the blue 24mm version from ISOfrane.
