I know, this is SK forum, but probably more CPH knowledge here than at the neighbours

What is the general opinion, can I do a HEL-CPH-HEL turnaround on AY?

The reason I'd be doing is that ex-CPH AY has much better Asian prices. Also the incoming is part of a XXX-HEL-CPH (where I took on the CPH leg, because it's just cheaper than terminating in HEL) but I could utilize the otherwise useless HEL-CPH leg as well.

Of course I could take a later CPH-HEL as well, but I'd rather just take a morning turnaround and have the rest of the day at the office than hang aroud in CPH a few hours.
