I highly recommend the Go Sports. Definitely get the open heal fin and get the low ankle booty for warm water. I use a 3mil short booty in warm water and an 8mil regular booty for cold water with the same fins. The Go Sport or Go Sport Gorilla are great all around fins. The Gorilla are a bit stiffer, I like the slightly softer Go Sport due to calf cramping with stiff fins. No assembly required and they fit in most carry on bags.
