That's great news Rod! A couple of more focals to use is "spear wide", and "spear deep" (below the lungs) on breathing stroke, i.e. spear wide/deep with left arm as chin follows right shoulder to air. This will help avoid over-rotation (spear wide) and maintain balance/stability (spear deep and wide). Often when we go to breath, it's natural for us humans to scoop spearing arm high toward the surface and reach narrow in front of head. Both cause instability and body will sink a couple or more inches - especailly us guys with heavy legs/hips.
Good luck - and enjoy the journey discovering easy and relaxed breathing.
