After I discovered that the double-insulator stacking pins in the store both:
a) Aren't long enough to reliably socket once stacked
b)Require manual shaving down of the insulators that sit beside the 3.5/3.6 processor

I'll assume that this rules out stacking female sockets of standard thickness for the top of the 3.5/6 also. I'm actually surprised more people aren't having this problem considering it would apply to both the wiz adapter and the audio shield, unless I'm missing something.
Does anyone know of off-the-shelf procucts to achieve these things, maybe some kind of lower-profile stacking sockets and/or some dual-insulator stacking pins with longer legs?
