Female/female can be made to work with a much longer bolt to fasten the spacer to the tripod, so I'm not too worried. I need to buy a long 3/8-16 eye bolt to use to hold the head on, then I can also use the eye to hang weights or tie it down. And since the adjustments on my tripod can be a little crude, the leveling base might be nice. If I decide it is a hassle, I'll sell it. Didn't realize how much those went for new, so I should be in good shape for the price I paid. And at any rate, the second adapter is on the way, so too late to do anything else.
