I am a relative newcomer to spoon carving and was in a similar predicament a month or so ago. I opted for a single sided, right hand crook knife from Ben Orford. Like I say I have no real comparison but I got to grips with it very quickly. The handle is quite slender but seems to suit my hand. Also with regard to the single side, I haven't found it to be a disadvantage in anyway so far - means you can use your thumb on the back if you like, although again not found myself doing this much.
Anyway, usual no connection etc, there was a thread on here with a crook spoon 'showdown', the mora seems to come in for a little stick for a less than sharp blade out of the box.
Good luck
