Splitting hashing power to two pools, good idea?

[mdopro1]

I have 60GHs and I'm mining with Slush and sometimes I go to BTCGuild. Does it make sense to mine on both with 30GHs each? What are pros and cons?

New to mining so any education I get is good.

It definitely reduces variance.  If one pool hits a stretch of bad luck, all your hashing power isn't stuck not making bitcoins.

But you also reduce your payout per pool.

Still, with 30ghs per pool I can make about 0.15btc per day judging from my little experience.

Then I ask this, if I have 6 blades and I join up 6 different pools would that be even better?

In the long run it won't matter, but splitting hash power between pools can help with short term variance (somewhat).  I'm not sure how well this strategy works at the moment when you have BTC Guild with the lion's share of the network, while the second fastest non-PPS pool is only ~1/5th their size.  The writeup on splitting hash power over many pools is quite old, and I don't know if it made assumptions for splitting hash power between a pool with 30-40% of the network and others with only 4-7%.

As stated above, long run it won't matter.  Theoretically it reduces short term variance, but that *may* not be true with the current network distribution percentages.
