I have just started to dive with my doubles for about 10 dives and I think my trim seems to be okay underwater (slightly top heavy, but manageable.). However, I felt really uncomfortable to do surface swim. It feels like the tanks are dragging me down that i have to do ab crunch to compensate it. After 20 min kicking on the surface from shore diving, my ab muscles can be sore for days. Is it normal?
I'm 5'4", 120lb. I use steel double 100, Halcyon Evolve 40 wing and Halcyon small aluminum plate.
I don't think my tank band can be raise much higher....
Any suggestion would be appreciated.
