Glasgow angling has 'stillwater' as their in house brand so they would recommend them
In a nutshell, 90% of the cast comes from the caster not the rod so get a budget rod ( shakespeare/airflo/stillwater is fine ) and spend the difference is there is any on fly casting lessons.
The reel is just holding the line, so just get a cheapo.
A bad line is a nightmare so don't go too cheap on that, it's a real false economy.
For the time being focus on trout, salmon is very different and can be expensive, but by golly get into it later on! And leave the pike for now, casting a pike fly can be a pig so don't bother trying to run before you can work
Otherwise welcome, good luck, and take advantage of all the advice and good will on this forum.
