I'm a bit confused by your OP and the later ones. You started out saying you were leaning towards a recumbent trike, then later said you'd ridden conventional bikes in the past and were happy with them.
So it begs the question, not for me but that you need to ask yourself. WHY are you thinking recumbent trike? It's important because these are an expensive niche option, very different from what you're used to. I'm not saying they are a good or bad choice, but you have to ask yourself why you're drawn to them.
Like the others I suggest visiting a number of shops (2-3 is plenty) getting advice and doing some test rides. But before you do so, I suggest renting and riding for an hour or two at a minimum to refresh your memory of riding, and having a better sense of what you may want.
