Thanks for all the replies from actual users of these blocks! Here is what I have learned: 1) Both Indy and World have very poor customer service! 2) If buying one of these second hand customer service will not exist! 3) Both Indy and World need expensive machining to be ready to assemble! 4) Now I have heard of oiling problems with both which make me worried the most! I would like to hear and learn more! Thanks! MJ
