I could be barking up the wrong tree here, but for roach I think your rod's a bit overgunned and the hooks are too big.
A more forgiving rod is less likely to bump the fish off and I've always found that smaller hooks penetrate better than larger ones (nearly all my bigger chub, 5lb+ fish, have been accidental captures when roach fishing with 20s/22s in clear winter rivers, none of the hooks have fallen out) also, the smaller hook would be less likely to be hindered by the proximity of the banded pellet when striking IMO.
I've caught a few lower severn roach on banded pellets and found the Gamakatsu wide-gaped maggot hook to be a decent pattern. Again, I think the width of the gape keeps the point away from the pellet, so hooks the fish cleaner.
Could all be nonsense of course.
