hi carl,
i'm a piker too mate, very few of them in the tame to be honest i wouldnt bother fishing for them and thats not trying to put you off because i know something that i dont want to share its coz i dont think they're worth it at the moment,there have been small jacks in the past but i've not heard of any big girls in there.
are you a member of any clubs?

kev.
