What size vials to use for spiderlings

[rknralf]

I am planning on ordering some vials from Thorton Plastics for my spiderlings and was curious what size you all use.
I was planning on ordering the largest diameter to allow for as much growth room as possible.
Is this a wise choice? I'm curious what size you all are using for your spiderlings.

vials

50 dram are nice sized vials that will house a spiderling from hatching almost to 3 inches, though they are difficult to locate a tiny spiderling in if need be (if it's not wishing to be found).
Readers digest version: I like the 50 dram vials.
