Thanks for the help guys, i already have a 3-9 buckmaster and I think its great but there is a definite difference in clarity between that and even a vari-x I. Not that it's bad but it is noticeably a little less sharp. That is no big deal in the 3-9 variety but I would guess the difference will be exagerated at the greater power levels of the 6-18. I figure I'll give it a try and see what happens. Thanks again
