Andy -- I looked at Picasso Black Teams, the Cressi Gara 3000s and the Omer Milleniums....bought the Omers because I wanted replaceable blades, liked the fin pockets, and thought the prices on the black teams were too much for my budget, and the Gara 3000s (from DB store) required a huge premium ($50+) in shipping to get them to me. Plus, the Milleniums had been highly recommended by a buddy who bought them and loved 'em...and I was able to order and have shipped from source here in the US.
It definitely is taking some time for my feet to get used to the longer blades after years of kicking Mares Quatros (one of my favorite pairs of fins for scuba). Feet were cramping the first few times in the Milleniums, but now seem fine. Oh, I also bought a pair of 3mm Omer neoprene socks, and bought the fins just a bit large, to allow for the sock thickness. Makes for a very firm, yet comfortable fit...never feel like they're at risk of coming off or even getting loose, regardless of how hard I kick. Kinda wish they had a bit of an angle on the blade...that's only regret thus far.
