I arrived in Cozumel today, staying at Hotel Cozumel, and I rented a tank to do a shore dive to test my new BPW and also do a weight check. I guess I have put on some blubber because I started at 8 lbs and struggled to stay down. 10 lbs did the trick, this was with an AL80. I did not bring my flashlight, Gopro or SMB with me though. I have some tweaking to do with the harness but first impressions are very good, I don't think the wing size will be an issue
