Ah, glad you did a little homework before claiming a first ascent for shaun!
on the subject of climbing grades, my route was conservative @ 5.9. maybe the 5.10 climbing grade on your route can reasonably applied to the former route. what the heck -- i might just jackup the grade of the spagnut-lang route for posterity sake.
aside from any misgivings that i might have about your fact-finding ability -- you were obviously confused about route details before correcting yourself (sic). Still, It's pretty cool to hear someone repeating my routes though.
