I bought my strap from Gordy instead of Andyfran, but they both look like their straps are the same. My Gordy strap took one month to arrive, so I reckon Andyfran can deliver faster since he is based in Singapore.
As for the mount, string is better than ring/lug. The string is faxed fibre type - very strong and generally feels more comfortable in the feel. String also gives a slight extension which has some leeway before the leather begins on your wrist. For ring mount, there is no such leeway, and ring mount gives alot of friction type of feeling.
