Here is my take on all this, if anyone cares. Yes, you can make a pretty reasonable arsenal of Dynothane balls. Dryish conditions: Barrage. Light mediums, HIGHLY POLISHED Vendetta. Mediums with clean backends, Thing. Heavy mediums and carrydown: Element. Wet-dry: Vendetta Black. Heavier Oil or mediums with minimal backends: Vendetta Particle.
It would be very easy to have a complete arsenal of strike balls (for 99% of what most of us face) with only three of these. Here are the three ball combinations I would suggest.
If you prefer arc-y equipment:
Barrage
Vendetta Black
Vendetta Particle
If you prefer snappier stuff
Polished Barrage
Vendetta
Polished Element
To cover almost all of what you will see most completely
Barrage
Lightly Polished Thing
Element in box condition
