I had Mr Marlin hand pick me one tbe first year they were made . He played 8 calls and put 6 in his sack . when I went back by I ran all he kept and couldn't tell a dimes worth of difference in the whole lot . so if that speaks anything , they aught to be pretty dang good if they impress the designer , and did I mention he was an engineer all his life... Mine sits in the case with the 30 or 40 others of his I own ..
Just don't tell them about OUR secret though Richard ...
