I have an older weaker core solid Sonic X solid from Roto(.018 diff). I also have a Roto Rising Star, the Wrecker's gold cousin(diff .040). I also have a very similarly speced and drilled solid from Motiv the Ascent solid(diff .025) just like the Shout.
I will tell you my Rising Star is humungous compared to either my Motiv or my Sonic X solid.
I move often 3 and 3 deeper and have to be very aggressive with my Rising Star to keep in the pocket. It hits, and hard. The Sonic X if pulled will leave flat 7s flush in the pocket all day. 99% of the time. The Motiv 70% of the time. Both of these weaker cored balls must be spliced or slightly wide on a top hat to carry.
REgards,

PS both the Sonic X solid and Motiv are drllied fairly strong 4 1/4 inch pin to pap. Bowlers in our area are having great luck with the Motiv Ascent pearl I have heard on our wet dry top hat.(I have not seen) This ball specs up with the Scream
