ithinkican,
Not sure if you are requesting my direct response, BUT....
I just got back from hanging and bowling in Vegas over the last 2 weeks roughly... I went from hanging on the PBA Truck, watching the Storm/Roto guys throw (the DS), and talking about it with the guys on the PBA Showcase... The Defiant Soul looked cleaner than the Lucid, but had a harder arc.
Boomershine and Vic seem to do a good job of making their "Hybrids" feel exactly like half pearl/half solids (combinations pending, lol) feel like perfect happy mediums of their pearls and solids respectively.
Rhino had his DS with a pin buffer looking like approx 2" right of his VAL, with MB also semi-inline of his VAL, and an x-hole on the VAL relatively deep. I'd imagine for him since his PAP is probably relatively close to 5"+ it makes any ball with that layout try to have get into a strong arc by motion??
He (Rhino) threw it on the stub lane (as i've stated in other threads, I happened to be sitting on the stub lane next to Spanky, GT2 and while Rash, Rhino and Parker were practicing)
The DS looked like an exact fit between both previous Defiants. Smooth by comparison to the Defiant, more pick-up by comparison to the Defiant Edge. Altogether a greater distribution of ball motion than both of its predecessors combined.
If you are further curious about any ball motions regarding the other Roto pieces let me know.
Cheers
