I've actually had a 2 page resume and was asked for a full one by a recruiter
I have 10 years of experience too and mostly in consulting firms so I have many projects listed.
All the important information is in the first 1 1/2 pages, if they want to know more, they just need to keep reading
It may not have any statistical significance, but I got more responses when I've started to use the long version...
Anyway, I don't think a resume is the most convincing way to show you can do the job.
