My understanding on the Rip'D Hybrid was that it was too much ball - not in the sense of too much ball for the lanes, but for another reason altogether.
A lot of people were getting the same performance out of the BWBG than they were with the Rip'D Hybrid. Both are hybrids, but you know what you are going to get with anything out of the Black Widow line, especially as it is, as Tamer put it, "that well oiled machine that will last", versus the Rip'D, which is the overpowered muscle car. You couldn't go wrong either way, but as good as the BWBG is, you can easily see it cannibalizing Rip'D sales just from the name alone.
Is it worth it? probably, but seeing that BWBG can get you the same results, you couldn't go wrong either way. Personally, I'd go BWBG, but that's me.
