Question about Sinking during Underswitch

[garybarg]

I've been practicing TI Freestyle for several months now. Feel very comfortable with skating and rotating to sweetspot to breathe.

When I start doing underswitch, I notice that I sink a few inches as soon as I move my arm forward. Just does not feel right - seems like I get too low in the water. Not sure if it's just the way it will be for me (I am very lean, pretty muscular) or if I am doing something wrong. Keeping my lead arm between 4 and 5 o'clock in the skating position to keep buoyant and moving the recovering arm, during underswitch, to the same 4-5 o'clock position.

Thanks for your help,
Gary
