Rick,
I do quite a few spirits in pine mostly white pine and it carves beautiful. I have also done some in Jack Pine it also carves very well except it is full of pine tar. It some times takes a long time for the sap to get out of the wood. I carved a 100 year old barn beam about a foot square when I got into the heart wood the sap was still moist believe it or not. Yes pine is great to carve and the bark is quite easy to take off if you use a spud. Now I assume you know what a spud is, the old loggers used them to skin the logs. It looks like a really big wood chisel and is quite heavy. Hope this has helped good luck with the carvings be sure to let us see the final result.
Colin
