I would choose Big B IF I could get the old stuff supplied, Storm would be nice as long as I can get a few more Gravity Shifts first. lastly I believe they all make good balls its just if you match up to the ball. Storm tend to have a strong backend for me and seem to last a long time. Ebonite/hammer I personally am not a huge fan of especially since trying the green vibe. lastly Brunswick has had many good balls(rhino series, inferno series, avalanche series) They tend to be a bit earlier and smoother and rollier and are many times better for sport shots. These are my takes on each company asked about. Also Rotogrip seems to be on top of the game right now especially since the introduction of the cell/cell pearl.
