I have some of the normal boots from PB. They are OK, but I wish they went further up the ankle. I found that my previous fin starps would try to pull off the boot. I now have longer straps and this problem does not seem to occur. Tying the laces tightly is not always easy. I may still look out for some normal wetboots with a zip.They're the people I'm getting my suit from (and it does look lovely). I'll have a look at their rock boots, but I'm interested to know what other people's experiences are.
