Because of some health concerns I am forced to throw 12 lb. equipment for a while. I was throwing 14 when I had to stop for almost 2 years. I will be ready to start again in a few months and I wanted to put together a 4 or 5 ball arsenal. I purchased a rogue assassin but I have not drilled it yet. I am looking to fill the rest of my bag with some storm balls. I prefer symmetrical cores and I know storms mid -high performance balls all have the same generic core 2.65RG and .035 DIFF. Does this mean I only need to worry about the coverstocks when choosing a ball? I really like the NRG covers, especially the Marvel S and the HY-Road NANO. I was thinking about the All Road or the IQ Tour Nano pearl. The Hy-Road X is also on my radar. I was also considering an Axiom or Hy-Rad Max for a stronger option. For a weaker option I was looking at the Electrify pearl or the Tropical Surge. Has anyone thrown any of these balls in 12 lb?  Any feedback will be greatly appreciated.
