Ah, sorry, I was being unclear. Whatever you ultimately want to do, you will probably learn on two seaters and it will be during the day and in fine weather. It's just that once you have qualified, if you want to do more than that, you need a full international (EASA in the UK) license for conventional light aircraft. If long term you want to stick to two seaters, day, VFR (more jargon to learn!) then you have the microlight / VLA option.
Does that make more sense? If not, keep asking.
