I’d certainly recommend looking at the Drennan Red Range of rods for your commercial/carp work. I had a look at a few of them in the spring and couldn’t believe how good they are for the money (£49.99 I think from memory)
In terms of silver work, some of the Shakespeare range are very good for the money but having not seen them myself I don’t know which ones to look out for, but I’m sure others here will point you in the right direction.
Reel wise, again, I’ve heard lots of good things about some of the Shakespeare reels, while the Drennan Series 7 reels are also very good.
