Having never owned excellerators, I couldn’t agree or disagree with your comparison. I’ll trust and believe your assessment.Sibermike. I hate to disagree, but the extra doesn't swim like a excellerator. The extra is a Pro FF on steroids, bigger, stronger and meaner. The excellerator, can do almost everything the extra can, but does so in a refined, pleasant manner.
I've said it before and I think it's worth repeating. The beauty of FFs comes out when you flex them. The extra takes a lot to load up. The excellerator however has a taper profile that lets you load up the whole fin for go, or just the tips for really fine movement. Both have a place, but I rarely find myself grabbing the extras while the excellerators are in constant rotation.
However, my point was NOT that extras are the same but they are the closest you get to excellerators within the family. Thus, “comparable” (not exact or equal) characteristics. I based my answer on information provided by those who HAVE used both, including Bob and Blair when I was with them in St. Barbara years ago.
I would also point out that “loading the tips” for refined movement is something I do on every (ok, almost every) dive. Extras are “tip heavy” and the tips are quite easy to load without activating the whole fin.
Additionally, our Finnish friends are pretty “geared up” in my experience and will have no trouble getting Extras “fully loaded up” if necessary! I’m NOT trying to get them into extras over excellerators, however, trying out extras will allow them something to compare against their standard “board over the toes” fins. We’re only a 2-hour boat ride from Finland and I do have extras.
So! The best thing is for you to send me (free of charge, of course) a set of excellerators so that I can have them to compare to my extras. That way I can say, “Yep! You were exactly right!” I mean, isn’t providing a set of excellerators a small price to pay for vindication!!???
I’ll even do my part and provide you with an address in the USA so that you don’t have to pay overseas shipping! What a great guy, right!
