Note: the RS:Racing is fully compatible with the X9 and X6 masts

i was trying to check the boom length to figure out the boom and saw this just recently put in...after all the asking in this forum from you guys and great answers from the owner just recently crowned national slalom champ somewhere s.a. and again asking np if x6 would suit as an alternative mast than the super expensive x9 they finally gave in..obviously a lot of questions were directed on a lot of breakages to their x9
