You know, I'm not sure what size would be best. I have some in standard size, but it ties a slightly bulky Wooly Booger on a #8 aberdeen hook. I would think that the Green Weenie would be awfully stubby unless you use a 4XL hook.

On the other hand the micro is pretty tiny stuff which might look strange also unless two layers are used.
Medium would be too thick.
