Thanks guys.
I have mixed feelings about the orcs. They do look just like the Angus McBride MERP versions, which is very appealing. They are also cheap and multi-part with numerous conversion possibilities.
On the downside, the detailing is soft and it can often be difficult to find arm combinations and angles that don't look awkward.
In the end, the good seemed to outweigh the bad and with a bit of patience you can get them looking all right.
