No matter what Im diving (backmount, sidemount, with stages, multiple deco mixes, scooters or camera) or what my buddy is diving, I cant off the top of my head remember a dive when I wasnt waiting around for buddies to get ready.
Some have accused me of being a Type A personality. Really, its just that most of the time I have the option of being underwater diving, or sitting on land in hot or cold weather, with rain, mosquitos, or sunburns awaiting me. Id rather be diving.
I also know what Im doing with my gear, and dont need to fiddle around with it. Im usually the one packing the car, so I know exactly where everything is. Some trips Ive gone so far as to leave regulators on tanks, just unscrewing them, to reduce the time standing around putting kit together. Im not there to sit in the Peacock parking lot
if Im on the surface, Id rather be enjoying the nature trail, but my buddies arent THAT slow
I also enjoy diving both backmount and sidemount. Id challenge anyone who is a die hard sidemount diver, especially if you use big tanks, to throw on some lp85s, scooter back to Mainland, drop your stage, and start swimming. Thats the dive that convinced me to buy 85s, and my 95s, which I held in high esteem for many years, since I was only an OW diver, havent left the garage since!
