Damn, just when I think I've decided I don't want a vented fin, you have to
go and post something like this.  Before I get my hope up, I want to be sure
I understand.  You are saying that the Twin Jet Fins are similar in use to
Quattros for slower poking around the reef and faster and more powerful when
bucking a mild current.  How did they do in a stronger current?

I'm going to hate the answer to this, but what's the going price for
Graphite Twin Jets?  I can get the Quattros for just under $100 U.S.

I like my Mares Avanti TRE fins a lot, but am considering a foot
pocket/strap fin.  What I'm looking for is the ease of use, reasonable
length and light weight of my present fins and at least as much power and
speed when I need it.  Quick acceleration is as critical as eventual speed.
