The Edge is best avoided it is simply not good enough for 10 mts, the early pure match rifles FWB 300, and certainly the Walther LGR, are better buys than the cheaper modern options such as the MPR, they are just as accurate as the modern PCP's. The major difference to modern quality PCP's (Walther, FWB, Anschutz, and Steyr) from quality older rifles such as the LGR is in the ergonomics, ease of use, trigger quality, and the most significant factor is lock time.
For an expert with perfect technique, good trigger control and good follow through scores are not a lot different, but they are different, the modern rifles are not fashion, they are working tools, and top shooters will get an advantage as will lower level shooters but their technique must be good.
Come to Bisley next week end for the British Air Gun Championships and have a watch, my wife shot at international level 30 years ago with an LGR (which she still has), she's still shooting, but you won't convince her to go back to her LGR from her current Walther LG300 Junior and she's also waiting for an LG400 action to up grade that.
Good shooting
