Thanks for the replies folks, very helpful.
I always thought that VOLDAC was only for local residents, at least that was the case when I used to fish the loch many years ago, and as I have now moved to Glasgow didn't think this was an option, but will look into it. Appreciate the advice.
Lexi - thanks for confirming sea trout timings, and is more or less what I thought but disappointed Aug isn't producing any more. I used to fly fish from the end of July with my dad, and we did quite well in August in the 1980's both for size and quality (still silver) but not really been keeping up to speed with Lomond recently so was curious.
Not really looked at boats, and I remember the beautiful clinker boats McFarlane used to have. Just a shame they're no longer available. I didn't want to invest in a boat as I've nowhere to keep it hence I was looking to hire, but if VOLDAC is an option, then I'll look at that.
Thanks all,
John
