I can confirm that the Chinese sets are really poorly sized. I have a 7.8mm 7-pin tubular lock which I couldn't get any of the Goso picks to fit in.

It seems that they have labelled all the tubular picks up a size for some reason, with the largest '7.8mm' actually being about 7.5mm. They couldn't have been measuring the outer diameter, so I'm not sure how they arrived at that number.
The higher quality (though considerably more expensive) Southord 7-pin pick, was actually 7.8mm, and was able to open the lock in about 20 seconds:
