I have the 20-60x80 ED 2. I had both a straight and angled Ridgefield with me for a couple of weeks. The Ridgefield frankly surprised me at how good it is. Great scope for the $$$. The only thing I could nit pick with is that the fov really decreases fast with increase in magnification in the upper half of the range. Not a real problem as that higher end will be used (usually) to zoom on something you have already have centered and need a better look.
For the money, you will not be dissappointed with the Ridgefield.
