I believe that triplemining holds a relatively small share of the network hashrate, so they would probably have a considerable delay in confirming blocks. (I could be COMPLETELY wrong about this, I am new.)
Also, if you have not already, read the comparison of different pool payment methods on
www.bitcoinmining.com in the "Mining Pools" section.
I haven't looked into it, but I assume that triplemining pays in a triplemining system.
BitMinter uses PPLNS (which in my experience seems to be pretty fair). PPS is also a comfortable payment system for miners.
Here's some excerpts from
www.bitcoinmining.com/bitcoin-mining-pools/PPS: The Pay-per-Share (PPS) approach offers an instant, guaranteed payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.
PROP: The Proportional approach offers a proportional distribution of the reward when a block is found amongst all workers, based off of the number of shares they have each found.
PPLNS: The Pay Per Last N Shares (PPLN) approach is similar to the proportional method, but instead of counting the number of shares in the round, it instead looks at the last N shares, no matter the boundaries of the round.
Triplemining: Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which allows your share to grow faster than any other pool approach. The administrators of these pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. In this way, everyone in the pool has a better chance to make additional Bitcoins, regardless of their processing power.
There are many other mining pool payment systems at that URL. (Y)
