Before I begin I want to just inform you that no matter what pool you mine on, you should plan on staying there. The main reason for this is the amount of shares you have verified could be taken away from you and you could end up getting less than you thought. Another reason is the miner itself was not made for constant pool changing. The miner lasts longer with a constant run and just periodic maintenance. With that out of the way let us begin.
DASH PEER TO PEER POOL

You will notice from the picture above, you only have two mining pools that are in the green across the board. These are the only two pools that are mining according to the true protocol of the DASH Network. There are a lot in red, and for whatever reason they may be mining with unknown rules in effect. The safe bet is to mine on the two pools with the entire green across the board.
Keeping your miner on the pool and having patience is what keeps the network stable. You should understand that the shares you are mining will increase every 2-3 minutes on a DASH pool while a new set of transactions to verify may come in every 4 seconds.
The Global Pool network shows how many miners are on that pool network from other pools and countries. The more global pool network is showing, the faster your chances for getting a payout sooner. This is why it is important for you to stay on the pool so you will not throw off the work being done.
If you remember the article on how mining works you know that every share increase you receive every 2 to 3 minutes are actual transactions on the DASH network your miner is verifying. These are the paid shares. It is far better to keep your miner on these pools and get the constant share increase.
The only real thing you are competing for is the verification of these transactions, which miner gets them first, and which miner actually solves the block code to open the safe to gather more transactions.
You never really want to mine on any pool where you have a warning of unknown blocks being mined. This means there are some unknown rules that are in effect on that pool, and it may delay a payout longer that it would if you just mined on a P2P pool that is perfectly synced with the network.
Even centralized pools are not getting the reward systems a P2P pool receives. For those using a D-3 on a centralized pool your rewards do not add up as fast as it would using a P2P pool. You may get a daily payout, but the rewards are much smaller, and you do not actually know the rules and protocol that particular mining pool is using.
Even Zpool is a P2P, but they mine the most profitable coin at the time. The real problem that lies with the exchanging of the coin to the coin you want to be paid out in. The exchange will still cost you fees, then there is a matter on the minimum amount of coins needed to exchange, and the pool fee. You really are loosing money if you stop and think about it.
This is just food for thought. If you want to see the pools for DASH here is the link for you to see for yourself. http://www.p2poolmining.us/p2poolnodes/
In another article I will show you the types of pools to avoid when mining. I hope this information helped you.
