The Bull Whip came out in 1997 I believe. It stood at that time, and I believe remains to this day the lowest RG ball ever made, with a low RG axis rating of 2.431. I don't know the differential, but it must be high. I have two Bull Whips and got over 6 inches of flare out of both of them. AMF advertised it with a quote from Dick Weber saying that it was the best ball AMF ever made. Bear in mind, of course, that Dick Weber was their long-time staffer.
I found the Bull Whip to be an excellent ball and it remains one of my all-time favorites. It had a very smooth, controllable arc, but seemed to carry extremely well--making a somewhat distinctive cracking sound when it hit the pins. BTM mentioned in their review that it seemed to have a real knack for carrying the ten pin, and that was true in my experience.
I would imagine that on today's lane conditions, it would be most appropriately used on a light condition. You indicate that you are a cranker with average speed. I do not feel exceptionally well qualified to offer a bowler of that description drilling advice. Hopefully an experienced driller will respond.
