Couple of Questions About Pool Mining

[Golfmad]

Hi

I have a couple of questions when it comes to pool mining, at the minute I am using a pool that uses pplns 3000 and now they have an alternate pool that has pplns 100,000. Is there any benefit moving from the lower pool to the alternate? Im fairly new to pool mining so getting my head around pplns.

Also the mew alternate pool has significantly less miners on it, with myself only having 160mhs would it be more beneficial to go in with them or stick it out in a pool where there are numerous miners with 1+ ghs?

Thanks
