Personally I use a #6 octo 90% of the time. A wider GAP will give a better hookup ratio. That is a fact.
However, If the conditions deem that only the Perfect of Presentations will work, then so be it - Smaller size hook.

Chrome & Conditions can be funny.

SMALL or BIG both have their moments.
SMALL or BIG both have different prospectives ( Some call #10 big, Some call #6 Small) .... it's all RELATIVE.
Confused?
