Yo quickly tested this combo, as assumed 230 can still OS this relatively easily on both 230CS and D.
I will say this over and over if it isn't making sense.
230WD is just not good. 230WD is horrible in fact, if your opponent is so low that there is no contact between metal of 230 and 85, D is a very good choice. If your opponent is say BD145/S130, it is wise to use 230CS. However whilst I say this, both 230CS and 230D both OS 85 by a huge margin, 230D by a larger margin than CS. CS can easily OS 85, but at a lesser extent.
D is by a long mile much better than WD on 230, I can go into detail but I have video evidence as in my videos and a thread or two. Some might say WD on 230 will have a use - Everything
might, 230WD doesn't look like it if you were to ask any 230 experienced bladers.
D>CS on 230 for OS. However choosing between these two is unsettling, 230CS>230D in that 230CS covers a wider variety of non-230 tracked beys. 230D however can OS 230CS, a relatively reliable option.
Anyways D/CS malarkey isn't important, this information only comes into play when either/both are being unsettled, however my results show that both 230CS/D stand quite firm.
@Ink 230WD is such a failure that Dark 85WD was able to cause the increase of friction:sliding of WD leading Dark to win.
Arupaeo has the same results as me.
