Depends on the ball and on your release and delivery specifications

Roll. Will have some length, and probably a little angular. Since the ball and bowler is unknown it is a rough guesstimate. Roll is a guarantee.

Brunswick Slingshot...stroker, 250/300 revs ball speed not known but not speed dominant. Flat release, more end over end roll.

Length with some backend.

Without knowing the bowlers PAP it's not possible to know exactly but assuming an average PAP measurement of 5-1/4" rt up 1/2" then you'll get good length with a mild backend reaction.
 
The PowerKoil coverstock of the Slingshot is pretty strong but it is a pearl. Pearls in the hands of speed dominant bowlers do not normally work well.

The Slingshot's core has no considerable mass bias to exploit. Besides, I wonder what the span would be when the pin end up above the bridge and the (virtual) MB under the thumb. The span must be very small - is it a ball for a child?!

 

And, yes, some user stats would be vital - PAP, speed and RPMs would help. The Slinghot core is pretty mellow, and with a high track I'd consider this layout VERY weak - probably much length with a late and sharp breakpoint and a rather tiny hook.

Dizzy...my span is 4" cut to cut. As the distance from the pin to MB (virtua) is 6 3/4", it fits nicely.

As others on here have already alluded to, you will probably get a lot of length with a mild, slightly angular backend. Not much more.
