I went from the Anser to the Redwood and had the same problem until I realized just how much smoother and more accurate the Redwood is. No 30 ft scale messed me up but the 15 ft scale made up for it. The Anser forgave more but the Redwood is more accurate and after maybe 5 practice rounds you find it works quite nicely.
Something to try on those short putts. "Shape" the putt by missing perfect. Hitting early sends the ball left, late makes it go right (pull/push.) Don't change the aim. This is easier to do than you think because if you use the longer scales your backswing gets really short. This makes it very easy to snap your swing exactly where you want (before,on or after perfect.)
For instance, a 17 ft putt is only i avatar movement on the 150 scale, 2=34, etc. The avatar only moves a fraction and the meter goes very slow. Helps out swing-challenged sorts like me. I can't hit perfect consistent enough to save my life so I play to miss.
Hey, whatever works, no? GL
