i just used the trophy ridge matrix this past season.the vipin system' s claim to more sight picture (imo) is way off base.here' s my theory on that.excluding the top pin,if you were to divide the rest of the pins into four quadrants.you can only see left and right b/c there is pin stem' s above and below.with standard pins if you do the same you can see above,below,and to the left of the pin(right hand shooter).that is a 75% sight picture,where the vipin only yields a 50% sight picture.this is just my opinion and i personally know people who swear by them.the older i get the more i get set in my ways.
