Thanks!

Try: RippleScale = 0.18;

and use this:
/////////////////////////////////////////////////////////////////////////////
// Ripple Test #1
//
Out.Bump= (IN.Bump.xy * RippleScale) + (IN.Bump.xy += (vecSkill41.x * 0.02));
/////////////////////////////////////////////////////////////////////////////

That might get you in the ballpark.
