Decreasing at Armholes

[Mski]

Hi Everyone -
I'm knitting my first top that has armhole decreases - decrease at each edge every other row for a certain number of rows. My question is: should my decreases be k2tog on both edges? Or should one decrease be k2tog and the other be ssk?
Thanks in advance!

It sometimes looks more symmetrical if the dec at the beg of the row is SSK, and the one at the end is k2tog. That way both of them 'lean' toward the center. Or you may like the opposite - k2tog at the beg and ssk at the end. It's all in what looks good to you.
