Domain 301 redirects any advantage?

[rampzoid]

hi,

my ecom website presents itself reasonably well in all of the popular se's except, 'ms live' (for some reason?).

i was thinking about getting some domains (a few hyphenated)& pointing them to my main domain via a 301.

what are the current views on this? - any real advantages (or more importantly, disadvantages) seo wise?
also, i would not be doing this for the benefit of my extremely poor listings in ms live.

cheers.

Not questioning you tactics, but how will 301'ing help you in msn?
I have better luck with keyword rich domains with google than msn.
