When I look at their product pages on their web site, it just looks to me like they have way too many different products.
They've got their new "maple over carbon fiber" shafts they call OB Fusion. There are white ferrule and wood (classic OB) ferrules, and there are 3 different diameters/tapers under each. So there are OB Fusion 1, OB Fusion 2, etc. up to OB Fusion 6. Seems risky to me at a time when people are showing off their black shafts, but maybe there's a market for them.
They've got their low deflection shafts with either white ferrule (OB Classic +, OB Pro +, and OB Classic XL +, depending on the tip diameter), or wood ferrule (OB-1 +, OB-2 +, and OB-XL +). The + distinguishes these from the previous generation, which they also still sell.
Now they've got a new generation of low deflection shafts called S-line. They have roughly the same naming scheme and just add an S. So instead of OB-1 +, it's OB-1 s, OB-2s. Sometimes there's a space between the number and the s, and sometimes there isn't. And instead of spelling out Classic and Pro they abbreviate to OB-Cs and OB-Ps. Other than slight differences in diameter (11.75 for + version, 11.8 for s version), it's not spelled out how the newer ones are different.
They've also now started selling new standard deflection shafts, OB-SD, which they had never sold before, as OB started out selling low-deflection shafts only.
Although a lot of people think of OB as just selling shafts, they also sell full cues. And they recently released their jump cues and break cues, which I know are pretty standard for cue makers, but you add it all up and it's just too much. They need to knock out at least half of these products. It's not even clear if they sold much if any of these new ones, like the Fusion, S-line, or SD, before the bankruptcy. The release of all these new products seemed to coincide with the bankruptcy.
