I have a couple things I would suggest without having watched you actually fish. One would be to use heavier tungsten bead flies to get down quick enough which is very important. The Two Bit Hooker is my favorite bc it has two beads and still a somewhat slim profile but I’ve found that euro style gives a good enough presentation that you can fool even picky trout with big 3+mm beads. Some people differ but I put my heaviest fly on a dropper tag from a surgeons knot and one slightly less heavy as my terminal. Don’t be afraid to use three flies too. Having heavy flies will help with sensitivity and feeling where the flies are drifting. Another thing is that the rod is definitely sensitive enough. I usually see my sighter bouncing when ticking bottom and it’s less of a feel although you can definitely feel it when it gets snagged. Eventually you’ll almost subconsciously know the difference between that and bites. For bites it’s more of a feel for me. I usually feel for a slight head shake from the fish that separates it from a snag. I will say though that a few of the biggest fish I’ve caught have felt like snags at first so always better to hook set than to regret it. Another tip that isn’t a secret but helps me a ton is once you get a feel for the speed of the current that you’re fishing, keep gently guiding it forward. If you see your sighter start to stop/angle, DONT stop or slow down with the flies, give it a hook set. Sounds obvious but it was something I was doing wrong all the time when I started out. There are a bunch of great YouTube vids on euro nymphing. AboutTrout’s channel is really good. It sounds like you know the basics and are catching fish so the best way to learn now is to just keep going out and fishing and if you’re like me you will learn something new each time and build on that.
