Beowulf,
I think we must have been on the same trip with Coastal. My wife and I went out on Wednesday the 8th. and dove the Sherman. We got the same spiel that you did. I recall the "salty dog" of a DM saying 140 min. from the time the ladder hits the water, and he then went on to lay out a "dive profile" for those "Pumpin' air" as 30 down-30 up-30 down. My wife and I dove air and kept a solid track on the trusty diive watch. We both found that we were finishing up our 30 min down with 1200 psi in the tank. Yes, we would have enjoyed more time (especially the second dive-as my wife was hunting buried treasure...LOL). I think I agree with pretty much everything you said regarding Coastal. They were professional, the pre-dive was solid but yes...they had a "NO BS" time schedule and yep, they took off with Ladder still in the water...haha with the Salty Dog DM yelling...GO, GO, GO!!! like he was in a Tom Clancy novel...haha..
Otherwise...It was a good trip (specially considering my experience last year). 15-20 ft vis. saw bunches of Cuda and a couple tigers (adolescents). My wife and I would go again. Now, if Express is less time pressuring then I will definitely consider them.
Say...you weren't the fellow Yanking on my Regulator that last dive were you?..LOL.
