Do you keep your head above water Bobg? Allowing the head to dip under allows for a much more efficient and fluid stroke.
Concentrate on the legs part of the stroke, get that smooth and powerful and you can faff about with what you do with your arms while motoring along using your legs.
Be careful to not split your kipper when first entering the pool. Warm up your groin area slowly.
Arms? Trace a large keyhole shape from full extension and then move them forward underneath you quickly*. The keyhole is mainly used when practicing good technique as when in proper swimming mode it don't usually look like a keyhole shape.
*This should be the fastest part of the whole stroke and the only time you should create a splash.
Smooth fluid strokes are much faster and efficient than thrashing.
