Well, had Roy's Zero-S on the yammie-block for awhile now and it's holding up rather well even tho Zero's rather a bit heavy actually (compared to my other valks).
Still, I'm a little leery of the peg-socket sliding to the side on its own coz of Zero's weight, so I'll prolly replace him onto my Yammie-Arm when it finally gets here and then put my YF-19 on the yammie-block instead since it's lighter.
As such, I don't have the Ghost to do the add-on, (well, not yet), but I think it'll be interesting to know if the Yammie-Block can actually hold up the Zero+Ghost combo weight.
Nevertheless, here's my Roy-Zero chasing Nora pic. Ever the ladies' man, I say...
