i'm a new member but have spent the last eight years fishing for specimen stillwater roach - often five short sessions per weekBeen speaking to a few lads on another forum and the general consensus is that the feeder gum must go as it acts as an inertia recoil string and serves to bump fish off, as Mark has also just pointed out. I included this to try and compensate for using a rod that was stiffer than I'd like, but hadn't really considered this problem.
Also, the flexing of the hook seems to be a common problem others have encountered, and so I think some thicker gauge hooks are in order. The regularity in which roach take static barbel baits on the river I fish gives me confidence that the difference in presentation will have negligible impact.
There is also the issue of the way I generally bring roach to the net i.e rod high rather than low and to the side. Apparently playing roach in this way limits the way they shoot to the surface and roll, and you can get them to glide in with less of the jagged head shakes of which they're renowned. This is something I'm going to work on next session.
I try to match the weight of the feeder to the flow so that as little extra resistance causes it to dislodged as possible. I've found this to be around 15gr in the majority of the areas I fish at normal river levels. I set this up free running on a swivel bead to a quick link and attach the feeder. A couple of beads are then place above the hook link swivel to kick it away from the feeder. Nothing more complicated than that really, don't like to use complex rigs as a general rule, as I think in most situations they're a hindrance.
Thanks for all the feedback so far. Is the above in line with your experience when tackling roach?
