Hi,
I've used both splits and non-splits and, in my dotage, tend to prefer splits.
However, whatever fins you choose, let me make one modest suggestion: add some spring straps to them. These are the easiest straps to both put on and remove. I first got wind of these from the DIR folks and gave them a try: they were worth the price of admission. This is especially true in the case of shore dives where surf or surge makes entry-reentry a "fun' experience. And, I found them to be preferable for boat dives, as well.
