Well Sanso, indeed 10 different awsers are possible, but not all of them are likely
These days I can take a lot of air with me, I guess arround 6,5 - 7Liters and at the surface I'm 3kg boyand. If I where to dive without suit to 10m and I would go full lungs, I would not
need any weight(s). I would make one good duckdive, two strokes and glide the rest slowly down and find myself just slightly negative or about nutral (not floating up). Good enough for watching wildlife, experiencing the pressure, relaxing, enjoying the light etc. Perhabs If I were hunting I would like to have one or two kilo's of weight, to make ik really easy to get down and duck behind some cover to catch some fish. But going up would be heavier, especially with short or no fins (could even be scary !).
One of the first freedives I did was with an scuba suit on and plenty of weight. I went down in the med to about 7m and find myself for the first time Negativly boyand! It was a scary, "oh shit" experience. With my big open heeled fins I could push through, but at the surface it was like, I have to much weight!. I whore a 7mm suit with 6kg of weights diving with my brother.
In general for practising I recommend NO weights, even with a suit. Than you'll become really good and efficient in duckdiving and waterentry in general.
But offcause your buddy can comment on your technique and results too
Buddy, courage and water,
Kars
