To be totally honest, the item drop buff isn't really worth it. The standard values already nearly guarantee rare drops as it is with double Zelnite/Zeruiah Leads, and the extra 2% is literally worth only that, if not less, in the final calculation. Not to mention, that SP skill still only makes him match Zeru's 7* drop rate boost, so it's a wasted buff if you have some Zeru friends still once he comes out. You're much better off picking one or two of the other options that further increase his combat effectiveness, which will even make him good as a sub unit when you're not Leading with him.
