Hi , I'm guessing you didn't like Theale because you didn't catch , at £11 / day it represents good value around here ( Reading )for the fish it contains . I don't think you will find many places under a tenner and if you do they will be awful little places that you wouldn't want to fish. There is a place at Aldermaston called Court Farm 3 lakes to chose from and you should get a bend in the rod .
From what you said be careful where you chose to fish because you will only get fed up when you blank , I fish the Island lake at Theale and its one of those places on paper that looks easy enough but isn't . Believe me your not the first to leave there dissapointed .
If you can find somewhere that you like and can catch at stick with it for a while , build up your skills . Catching bigger fish can be more rewarding but as you are finding out it's harder and can get realy expensive per fish caught . Good luck.
