I've bitten the bullet!
So I went diving yesterday and one guy had the new Scubapro Go Sport fins which are basically identical to the Go Travel fins but designed to be worn with boots. They're very light and compact, I liked them.
I compared the blade with the Seawing Nova (which every dive master seem to have nowadays). They both behave pretty much the same way, bending to 45° when you kick down (good for flutter kick) and maintaining the shape when you kick back (good for frog kicks).
They both have a similar sized blade but the Go Sport is more compact and lightweight.
So I went ahead and ordered a pair of the Go Sport with a pair of Tusa low cut boots. I'll let you know how I like them after a couple of dives.
Cheers
