No 2,3,4 & 5 In Serps

Should I 301 4&5 To 2&3 to go for top spot?

There is an exact match .com domain which sits atop my search. Frankly, it's not budging unless bigG decides to turn the knob down (now and agin) on exact match domains, which doesn't seem to be as often as it did a month or two back.

I am no 2&3 in the serp with my main site, but fortunately I have an exact match .org in 4&5 too.

Anybody here with a view on this?

I know, I have 4 out of 5 spaces at the top, which is in itself useful. But it's a bit spammy for my liking and I'd prefer to strengthen my main domain - in fact, I'm in the process of 301'ing two other sites to the main domain, as the brand is getting stronger on the main domain, and I cant be bothered with 5 sites for the one service.

I'm thinking of redirecting the exact match to my main site.

Will I lose the usefulness of the exact match as far as Google goes if I let my main domain absorb it?

Will my main site be strengthened?

Should I forget this, and keep trying for the top spot but without this particular 301?

Any comments greatly appreciated!

Of course another option is to further promote the .org exact match, but I'd ratehr I was concentrating on one domain if poss.

I took over a site with 4 subdomains that were just spammy duplicates of the main domain, created to catch the keywords of the subdomain.

301'd the subdomains to the main. Soon after, and until now a year later, the domain ranks #1 for 2 of the keywords that were the subdomain name, even though no links, text, or scarcely any mention of those keywords exist.

Sure seems to me like G keeps a record, and gives "credit" for what a site is about for a long time after it has been 301'd.
