Philip.....it's not the bankside vegitation that matters, try to think about what is in the water and whether you think a large eel would nosey around for food there.
Personally i would stay put and get used to your swim during the daylight hours, at least untill you you become more experienced.
2 rods of 2lb tc is a perfect set up, as is lobs on one and deadbait (use halfbaits)one bait or the other may prove the best, only time will show this.
They are catchable during the day but in general your chances are far better as darkness falls and also make sure you have decent baits still on anhour before light and as dawn breaks......these can be very good times.
No problem about "all the questions"!
Other tips......do not use massive hooks, you will cause damage to the eel.....sizes 8,6, and 4 are ample.
holding the eel upside down on a wet mat etc can help to stop them wriggling and aid unhooking.
Pick a warm sultry night for your first session.
Do not try to play the eel, hook it and land it, if it reaches a snag it will die before it gives up it's hold.
Good eeling!
