In both condition emma but in surface more.Are you tilting forward at the surface, or while horizontal during a dive?

Thanks I am 105 kg and using XL size it is oversize on shoulder area but fit round of my wrist. I am using 24 lb weight. Till now i was putting all of them on my bcd weight pocket but i am planing to put 10 at trim pocket and rest at my weight pocket to get better balance. Do you think this distribution is ok?Depends how much weight you have and where it is. If you're using a weightbelt, your body is negative and the BCD is positive, so you tend to fall through the BCD- especially if it is too large. Often people are wearing BCDs that are a size too big IMO.
With integrated weights, the BCD is more balanced by the two opposing forces.
The initial post stated that the OP didn't like a jacket-style because it squeezed when totally inflated. You shouldn't have to totally inflate any BCD while recreational diving. As someone pointed out above, you should try to lie back at the surface so the BCD bladder is underneath you- this requires you to stabilise yourself using your hips or fin movement. It'll come with practice.
The trim-pockets are excellent and I wouldn't buy a BCD without them. Don't overload them, but use them and you'll really see a difference to your trim underwater. On the surface, they may only add to your problem... which IMO comes from over-inflating the BCD.
