Anticipating the arrival of my BM JP:jet pack..looking into getting an aluminum hollowed beacon and stabalizer set. Does anyone know or have any opinions on the different and accurate sizing of the various beacon/stabalizer sets offered on this site? (TO fit the BM JP accurately, if there is a major difference?) am looking at getting psberetta's version, wondering what other BM JP users used? Anyhelp/comments/pics? jjv5150 ..thanks ...confused
