Since the minimum RG (15 lb.) is 2.52 and the Differential is .053, I'd look for any light bulb core with a flip block in that range.
those kind of numbers sound like a vibe to me. look at the viral hybrid or viral if you can still find one
The Adrenaline Overload being a pearl with 2.50 and .056 seems close. Does the Ebonite line have an oil saturation issue that kills their cover stocks faster than the other EBI lines? Never thrown them but have seen it pop up on here.
What modern/current core would be considered closest to the Lane#1 Bomb core in the Dirty Bomb? I love the ball and would like a modern day version with a slightly stronger Pearl coverstock.
