Hi ya mate, I would stick to Andersons if I was you for Tench, the lakes are up a little at the moment because of the rain, but they should soon be down again, they don't take long to drain off.
Your best bet for Tench would be the bank behind the Ivo lake, where you can walk between the two lakes and one of my favourite pegs is the one on Andersons where the channel meets the main part of Andersons behind the corner of the Ivo lake, it's about 7 feet deep in the channle half way across and I would float fish there, or near the lillys and reeds at the back of the channel. But to be honest all the pegs in that channel are good, and I normally float fish, as it's not very wide or deep there. Take some expo groundbait mixed with brown crumb if you can add some crushed hemp or hemp, or halibut pellets, throw about 3-4 balls out at the start of the session. Then just lose feed after that with whatever hookbait you decide to use red maggot and caster are good early season, as is sweetcorn, but I have found lobworm to be the best hookbait, maybe because it floods a bit and they are probally used to seeing lobworms. I find they can bubble up a lot but not touch your hookbait sometimes, when using maggot, but put a worm on and you usally get a bite straight away. My other top tip is get there at the crack of dawn if you can, as they tend to feed really well from about 7 till 10ish then it can often go pretty dead all day till the next morning. But you should get a couple at least this time of year, my best catch is 12 in a morning and lost a couple and they avarage around 5-6lb with my best just under 8lb.
Hope that helps ya mate and I may see you down there, good luck and let me know how you get on, Lee
