I understand that logic and appearantly everything worked out for you. A couple of things tho.
I'll use mask clearing. You learn to remove, replace and clear you mask in the pool, that's great, but I'd rather have the students learn to do it with hood and gloves on because that's how they'll do it in the ocean/lake. I'd don't want the students getting all frustrated or panicy and bolting because the 1st time they did it with hood and gloves and they can't get the seal is in the ocean.
With bouyancy. You get weighted in the pool with no suit, then go to OW with 14 mm. Yeah, you can guess-timate, but it's just easier to have that stuff figured out before hand. I mean, here the student use the full suit in the pool and we have to adjust when we go to the ocean because now it's salt water....add 3 or 4 lbs. We still end up with student that have gernades hangin all over their bc.
With me, it's kind of a "be prepared" thing....like when people show up for the 1st pool session..."oh, I need to rent my reg and get tanks still"....Dude! you've had all weekend, the Instr said on thursday in class to get your stuff BEFORE you show up at the pool on tuesday.
I also wear a 2pc in the pool, 78 degrees. I have never been too warm. I do vent the collar to let water in from time to time tho.
Hey, whatever works for ya, tho, right?
