"It seems a pretty subjective debate."
Not really facts are facts. I believe there is a report compiled by the English after Waterloo of all the captured French ordenance, and not one 8 pdr (if I recall correctly) was listed.
As for sources, here is a short list. Sorry, I no longer have my book collection anymore, and my HD has crashed several times over the years, so most of my research materisl has been lost.
Nafiziger's books, Bowden's books, Army oobs found at Nafziger's site, Geert's excellent site

HPS' Campaigns Waterloo, NRC, Wagram and Eckmuhl OOBs (all were extensively researched), "Empires, Eagles and Lions", the website Napoleon Series, to name a few.
(yeah, yeah no original source listed specifically, sorry, others in this club will be more than happy to supplement this list with properly referenced primary source material.)
The French introduced a new arty system in 1805 which took several years to fully implement. By Nap's invasion of Russia in 1812 the main army was armed with equipment prescribed by this new system. Secondary theaters and the main army, after the losses sustained in Russia, still used older systems, but in 1815 the new stuff was back. Faulty memory but wasn't the system called XII? I'm getting forgetful. *sigh*
Since Napoleon considered Spain a secondary front the older Gribevial (sp?) system of 8pdrs and 4 pdrs was used there. As this is where the English mainly fought, English historians drew conclussions that the entire French army was equipped as they were in Spain. These conclussions persisted over the years and greatly influenced Napoleonic wargaming in the '60's, but over the past 40 years new research has improved our knowledge of the era.
