Hi Willie, tried the Tulcan link but got redirected to "innertopia.com" ?
The Tulcan beats are the last word in luxury ... exceptional bankside maintenance, great ghillies and fishing huts so well appointed you could quite comfortably live in one. The lodge itself takes the concept of luxury to onto another plane altogether! For slightly less $ there used to be some cottages which were also very nicely appointed but I'm going back 10 years. This is also prime single malt country!
The only other river I had any regular experience on was the Tweed in late November down at Yair (sp?). Loads of fish moving through at that time but takers were always very scarce. I managed two fish for four weeks over a fiver year period. Having 20lb plus Atlantics in full spawning livery jump out so close you actually make eye contact is quite exciting however!
My general recollection was that prime beats at prime times are not only expensive but "dead men's shoes" to get in. Prime beats at non-prime times were often over-priced.
