ASA Rule; Access to,

[topper]

I may be wrong to do so, but I feel there is a distinct difference in ASA sanctioned tournaments like qualifiers, regionals, etc. and non ASA tournaments being played by ASA rules, which is the case in the OP. The former absolutely should require ASA "certified" officials, while the latter only officials with ASA rules knowledge.

As to mechanics, I don't feel any obligation to use strickly ASA mechanics even when working ASA sanctioned tournaments. While one rule set may not be fundimentally superior to another, some mechanics are and I will use those that make the most sense and put me in the best position to success.
