Good advice from Mr B.
The fishery boss is usually the best source of info, especially one that knows what he's talking about.
If the lakes have a shop even better, should be able to help you out with tippets and leaders too.
How you fish the flies is more important than the pattern, find out where the fish are getting caught and perhaps what speed people are fishing, most anglers who are catching fish like to tell the fishery boss how they caught the fish as well as what on(infact i would go so far as to say they probably dont fib about technique as much as flies
)
Damsels, black and green lures, mini cats, black buzzers, bloodworms are all good at this time of year. It'll be different to the Highlands , but adapt and you'll have lots of fun.
tightlines and big smiles
