In order to use the i70 head/weapon on your retainer and still have one for yourself, you'll probably want to buy yours then get the next 60/30 HQ whatever items. Once you're ready to buy the 2nd ones, drop the existing i70 hat/tool on your retainer, then go buy yourself some new ones.
If your retainer is a FSH, I don't envy your task of catching more of those fucking fish though.
