Hi Skidd,
I've bought the roving ticket for the last few seasons and it's an absolute hit. Four really nice beats with lots of water in which to fish for brownies. I typically fish Kintore because its nearer home and my mate prefers it (don't get me wrong it is a very good stretch in it's own right) but I had a walk along the full length of the Inverurie beat not so long ago and it truly has all the characteristics of a good trout fly water - I'll be spending more time there this season.
Alford has two great beats that hold good memories for me (caught my largest Don Brownie there) but, although its not exactly the other side of the world, it's hard for me to drive past Kintore & Inverurie - lazy boy!
The real bonus is that you have the flexibility to fish when the conditions suit you, whether its only fishing the first few hours of daylight, catching a rise, or fishing the last hour on a summers evening when the big boys seem to come out to play, you are still getting value for money.
As for the Brownies themselves, I can only speak for my own catches and I find that 1/2lb trout are reasonably common (and I'm happy to catch these all season), 3/4lb trout are not uncommon, 1lb - 2lb trout make an appearance now and again with the odd 'specimen' popping up to give you a season to remember.
Hope this helps
Iain
