I recently picked up a VFJ primary and love it. However, the secondary clunk and rattle seems more annoying than ever. Probably because I am hearing it more now that the noise of the stock primary is gone. So I have decided to pull the trigger on a STM tuner secondary to solve the noise problem, and for the added performance benefits. I would like to find someone who has this exact combo to discuss setup of the primary. I spoke to John, and he runs this combo on his Renegade. He offered his advice for general setup. I know I will have to lighten the base and add weight to the tip. Hopefully there is someone who has this setup on an XMR with 30's that can share some advice. Also those of you running QSC primary's that later added a secondary, feel free to chime in regarding how much adjustment was need versus setup with the stock secondary. Thanks in advance.
