I shoot d 97 on most all my bows if they are in good shape won't put on my 1959 kodiak, have one on a 62 kodiak, have them on over 20 vintage bows, with these strings shoot heavy arrows on old bows. I pad the loops to 20 with b50 to pad the loop cut the b50 to 16" I use 2 different colors, wax the end of the d97 good then on the first 4 strans seperate and add 1 stran b50 to one stran d97 then put the bundel together ad last 2 strands b50, it takes awhile to make one, well worth it,good luck.
