Why not solid PVA bags mate, problem solved, feeder, big method, with a 2 foot plus tail.Other than that big flat bottomed open end sledge, why do you want an alternative, which river and do you have a problem.
Another tip around this is don't clip the pva mesh to the hook, try to attach it to the lead. I use a running rig where i have a swivel link on the line which is what i attached the lead or feeder to, you can then use the same clip on the link to attach the pva mesh. I make sure i use one of the knots to attach it.
The problem with this method in any significant flow is that the mesh bag can become unattached from the hook and then bounce off downstream with losing it's integrity (thus your pellets just bounce off downstream in one go). Attaching them to the link tends to mean that the mesh bag will burst properly - distributing your freebies just a little upstream of your hook.
Something else i've found is that by making homemade feeders out of gutter mesh, i end up with a flexible feeder that has considerably more give in it which i think helps it get out of snags more regularly. I fished side by side with a mate on stretch of the wye where he was loosing feeders and i was retrieving them, casting in to pretty much the same areas.
All of that said, i think some tackle loss is inevitable fishing that particular river. Never mind feeders, i get through loads of hooks - which seem to go blunt or have their points turned very regularly too.
Just curious, what mainline and hooklenght are you using?
i fish the wye a lot and its very snaggy im getting fed up of losing feeders and getting caught up so i tried a ledger and it wasnt as bad so i thought if i attatched a pva bag to the ledger it might be better
some of the stretches of the wye that i fish you can lose 4 or 5 feeders a day when you think that feeders are approx £2 each surely it must be cheaper using pvaBut PVA isn't exactly cheap. OK if your only casting out once every few hours, but casting regularly you could end up getting through a lot in one day? Will it still be cheaper than a couple of feeders? I've never fished for barbel though, not to even mention the Wye, so can't really judge, but it might be a thought worth considering?
