You dont need to book 2 weeks in advance before you go what so ever mate, it can be safe to if there are certain pegs you want but thats all. Whatever bait the owners told you to bring does`nt guarantee your going to catch what so ever either. Leightons a gorgeous pool and ive personally never seen a bad looking fish come out of there, every ones been a beaut, as for the fish with no lips, if youve taken a picture cant you post it on this thread, id like to see it, if it is true id say its got to be the only one in there like that.
