I have the LW 2M and I think it's awesome. The pin adjustment is extremely precise and the whole unit is very well made. I did do a Fitz Fiber (www.fitzfiber.com) upgrade to the sight pins using a foot of LD fiber for each pin, they are screaming bright and more durable that stock fibers (I do this to all my sights, not just the LW). I also got the lense adapter to add more protection to the pins: http://www.lancasterarchery.com/shop...oducts_id=7399.
As Greg alluded to the pin guard isn't very protective I may try screwing in a UV filter into the lense adapter this year which will totally cover the pins.
