Thanks for the tip Dave. I'm normally very buoyant plus I do my free diving in a 3mm wetsuit (with DSD, OW and free diving I'm usually in the water for for 3 hours; definitely need to wear a wetsuit). I've tried diving with 4 to 8 pounds and it helps.

Won't be going to the pool this weekend. Sister-in-law going on a date and I'm babysitting her kid.
