If you want to mine a specific coin then this is a good pool for that.
If you have no life, then take the time to set up and download multiple wallets, and sync them with their networks.
Then go and set up an account with multiple exchanges so you can convert your alt coins to BTC.
Or, find a pool that does auto-switching and mines the most profitable coin and pays out in BTC. you will pay more fees, but you don't need a wallet with every coin and account with many exchanges to eachage coins.
