Digger Pine

Anyone have any experience burning digger pine? Or bull pine, aka gray pine. From what I've read, this forum is somewhat east coast centric but there are a few Oregon/British Columbia/California/Colorado guys I've read that burn pine.

I've been burning lodgepole for quite a while and recently scored a huge supply of digger from father-in-law outside of Nevada City.

The few links I've found on digger pine have the BTU at around 20 mill/cord and say the firewood is ok but pitchy:

I'll be hand splitting and as I've read on here before, it's always best seasoned and dry so I'm looking at the next few years for burning this stuff.

Thanks

Its bark looks very similar to some pine that I made the mistake of buying from a local wood guy not long after I first moved here. It didn't burn as well as other species of pine that are more abundant locally. Even after sitting for several years, it didn't burn well. I hope you have better luck.
