Website URL question

URL name

[Berlin99]

I have 2 domain names. A sample would be as follows:
sitenameinformation.com
sitenameinfo.com

So basically one domain has information spelled out and the other just has info.

I am wondering which one should be developed. info is shorter, but information seems better, but it's longer.

I assume from an SEO perspective that spelling out information is better, but I am not sure. I just don't want to develop sitenameinfo only to find out that it was better to go with sitenameinformation.

Any thoughts or advice on this would certainly be appreciated.

TIA

hmm... waiting for experts

This non-expert says:

The choice between "info" and "information" as sitename elements is so very far down the list of factors that could seriously affect your long-term search-engine ranking that you've already spent more time on the question than it merits ;)

If you're looking at type-ins, shorter is better. But in any case you'll be redirecting from one to the other, right?
