Never used the stuff myself but would that hydrolastic in the heavier gauge be any good, more of a question than a suggestion. Seen a couple of articles on it and a lot of people seem to be using it on carp puddles now.
These hit and hold poles should take a 22 no probs though, just balance your line to it.
Wasn't thinking there Carl, the heaviest elastic I've heard of is 20, but my pole (ahem) hasn't seen the light for a couple of seasons now, so I've not kept up on the subject. Could be up to 30 for all I know.
