hi josh, where abouts in southampton are you? I live near hedge end and if you are willing to drive this way there are lots of small lakes which would be ideal for beginners...River Farm in Titchfield, Newlands in fareham.
Broadlands is an excellent lake and can produce some crackers but not ideal for first timers...stick to small lakes as fish will be easier to find then when you get your skills up then hit broadlands and bigger lakes.
as i say, im hedge end way and am usually on the bank most weekends...even at the moment so if you fancy joining me I would be more than happy to give you some tips
cheers
