Bob- you know I love you, and the OPS were very cool fins, but you know that the Excellerators fit my style better. And the hockey fin... since I didn't get a chance to call you today and remind you... THANKS AGAIN, I love just looking at the picture and dreaming how awesome it is going to be.
ickis- the foot pocket sizing of the OPS is the same as the Excellerator, so I am unsure why you think the OPS will fit your smaller foot and the Excellerator will not. With a small foot, you'll probably still wear and L or more likely and XL with most booties. If you wearing heavier military style boots (OTB's or similar) it may even be a XXL. I think the Excellerator is the most versatile fin that Bob makes, it flutter kicks wonderfully, it frog kicks fantastically, it can hover, helicopter, and scull very well, and although the OPS is a great fin, it doesn't maneuver as well as the Excellerator. I know Blair loves his and I even think Avi has come to love them as well.
freediving- I used to freedive nearly daily (normally to ~45-60', but regularly to 100+), its how I used to catch my dinner. although back then I was using my Extra's, I have converted over to the Excellerators for pretty much everything, I just really like the way they work and feel and are just my personal favorites now. These days, I do less free diving and more underwater hockey which involves both surface swimming and bottom swimming at near max speed. The Excellerator rocked in this environment as well (which is why Bob has been modifying an Excellerator as the base for the new Hockey Fin).
