Hi, welcome to the Visionary users.
As Barry and Tommy said, Visionary tends not to do much in overlapping their ball release reactions. They like to fill in gaps in their ball lineups, but because most of us bowl on THS patterns, I think the balls will look like they do overlap a bit more than they actually do. You may notice this more between different lineups, like between some Ogres and Gladiators, but in each set, the balls should give different reactions.
Read what VBP says about their releases in their promo materials or on their website and use that as a guideline. If they say a ball if for heavy oil, it is. If it is for lighter patterns, it is.
Since you are now a member of their test staff, don't be afraid to call or email VBP and talk to Jason or anyone else there if you have any questions about how a ball will fit into your arsenal. They are very helpful, just like Betty is.
You can also ask various members here who are very experienced with Visionary and other balls, such as Charlest and Scotts33, just to name two others who haven't posted here yet.
If you're a new member, get a G-3 and Frankie May before they are discontinued. They are both great balls to own.
