I once sent a recruiter one version of my resume, then made some changes based on his feedback, and sent him version two.
He forwarded BOTH versions to the prospective employer. Fortunately the two were consistent.
It would look bad if you describe one former position a certain way to show management skills and a different way to show tech skills....if you went too far with that, it would look like you're just making stuff up.
On LinkedIn I have lots more stuff than is on the resume....
