I think that if Mick's jolly is within your budget GO!
We've only spoken on the phone but his enthusiasm for the sport was memorable. I've two of his rods which are lovely things, so take enough dough to take one home with you.

Nice, easy trip from Barrhead, too.
If you ever want some sport with the kit you already have, try the Scottish west coast and islands. A 10 ft 7 wgt is just the job for spate river/loch fishing for grilse, and £10 - £20 a day will get you either on the Isle of Lewis, these days. You'd need more than a couple of days to make the trip worthwhile, though.
