Hi Stamps ,welcome to the Uk, started off well with fish, looked a nice beat
gentle wading fair pace of water. All the things the Spey & Tay are not.
You will need wading stick, back support as they will be more physically challenging , they have larger fall from head to mouth so the bed is of more of a steep slope.
Sad about the lack of long lines, sign of the times, less effort less practice required.
Have a look on line at John Norris or Sportfish they have loads to pick from.
How long before you need to be back in the SMOKE ( LONDON )
There are plenty of quality waters between you and London and if you have time you should take a look.
PM me I will give you some contacts for fishing and accommodations
Having been to US and Canada , been looked after by locals very well, this is the least I can and should do for a fellow angler.
Have fun speying
