70 comes back pretty smooth for me, so I don't mind it for a 3D bow only, especially when you are only shooting an arrow every 15-20 minutes like in 3D. I would never shoot this much weight though in spots or for FITA, my Apex that is on the way for that has 60lb limbs. Also, at all the local shoots as well as IBO for the hunter class, regulations say 4" fletch and screw in points, and it is extremely difficult to get a line cutter style shaft (like a pro 22) down to the 300 grain area with a 4" fletch and a screw in point so that you are still getting speed at 60lbs. I also don't have the $$$ right now to set up a bow specifically for ASA events, otherwise I would have one that was at 60lbs. When I finally step up to open or mbr, I will drop down to a 60lb rig though, since it is easier to to get to 5gpp w/ short vanes and glue ins. For now though, I really like getting the speed and shooting around 5gpp.
