5 hours for £70 I would take that quite happily any day, I fished for years before getting lessons but only because they were £45 per hour.I did a free Orvis lesson followed up by a day on a stillwater with Orvis (they charged about £70 for the lesson I think). Now I am learning by doing with mixed success!
If you're close to Chew then you can get a 5 hour lesson for £70, which includes to bank tickets. So 5 hours lessons and some fishing, plus two further days on their water with no fishing. A day ticket at Chew is over £30. So that's a cheapish way to get another lesson. I will probably do that this season (or next if that's the soonest I can with this covid).
I know there's things I could improve on but on the whole I can put out a nice tidy line.
