Digging up an old thread for my first build. I am building a bt1083m and will be using a vs150 with 40lb samurai. Based on the suggestions in this thread and others, I am going with k-frames 25j-20j-16j-12j-10j. Will start with clamslingers spacing of 8",16 1/2", 28 1/4", 42 3/4", 59 1/4" and tweak from there. Any input would be appreciated.
