Wow amazing replies thanks I will be going for barbel but my main aim is to catch a river carp pre baiting and time is on my side so not worried there I've been told the stretch above Tewksbury is a good bet as there was a carp pool now Upton marina which emptied into the river when they created the marina opening. I will pm the two others be nice to chat and I'm not adverse to a companion I like abit of company.
On the tidal front I was under the impression carp thrive in brakish water as per the Belgium canals some massive catches their I believe carp are caught it's just these river guys less inclined to give away their secrets;)
