MLD URS, most of Attack/Defence is useless. MLD URS has LRF (near exclusive to it), XF and RF, along with 85, and the awesome looking purple LDrago Absorb. That said, it's honestly not THAT great, but it's a much better buy. If you have CH120 and a metal face (you can get away with MF-H, if you need to), you can make MF Meteo L Drago CH120XF, and if you've got the rest of the parts, MF LLD BD145LRF is amazing.
The addition LDrago CW's are useless, but they do look cool.
So yeah. MLD URS.
BB-86 has S130MB and RF as it's only useful parts. MB isn't all it's cracked up to be, and S130MB is rumoured to appear in an upcoming multi-blade set (though that may well change). S130 is nice, but WA130 and 130 are fine as substitutes anyway, plus S130 is only great for a few things. RF is, well, RF.
