The FR10 demo uses neatly separated spacers. The other candidate uses our delivery tray, with a few spacers leaning. Both clips look promising. What can we fairly compare before asking for another trial?
I'd ask both to work from the same incoming condition, including how they handle those leaning spacers, not just give the second supplier a tidier tray too
Will the person who normally fills the bench be involved in that comparison? They'll know whether the proposed preparation is a quick task or somebody else's full-time favour
