Thanks neilmny.
There are some more in trhe Gallery with a link to quite a few fast and slow comparisons, althoughI'll admit it leans toward the slow

Couldn't be bothered sorting them all out so I posted a link to the lot, the good the bad and the ugly
Not sure why the difference in sheen, it could be one of many things, some I used a Polarizer and some I didn't, some had mist on the lens and some didn't, had a terrible time with the spray.
I'm just glad to get some ok ones from time to time.
Once again, thanks for the comments, appreciate it.
