Wow, lots of good answers and food for thought. I'll have to pick a few big pieces from the "prime cuts" then a blanks of varying sizes/shapes with the rest. I'm sure some cracks/checks are inevitable, but maybe the random grain makes them a little less critical.
I was showing to a club member that came by my shop the other day and it really hit me the difference in the sizes of the trunk above and below it.
Well, I would start with that one beachball sized one that is looking straight at us. Plunge cuts at an angle in since they tend to be cone shaped. After that, kind of hard to say. I might just cut it down the center after removing that one burl cap, and see what it looks like, then section it up.

I get what you're saying, and I'm confident in my chainsaw skills, but plunge cuts are tough. I'm picturing cuts that don't meet up well a hacked up mess. Maybe I should pick a depth, cut straight across sort of pare off sides of it. (I'm guessing both safer and less wasteful)
All kinds of ways to cut burl but I really love the trailer on a Prius. Never thought of pulling my trailer with ours.
It's a lot lower than my truck bed. (for walk-behind mower, motorcycle, and now burls/wood) It started with a hitch for a bike rack and progressed quickly. Gasoline is about a dollar less than diesel and I get more than twice as many miles. Yea, some say a Prius pulling a light trailer looks crazy. (I say crazy like a fox

)
Burls are like the proverbial box of chocolates you never no what you're going to find inside them. I had a guy want to sell me an Ash burl (wanted $250). It was an awfully nice looking burl but I passed. I told him if he didn't sell it I'd like to be there when he cut it open (I wasn't there) but the results were weird. It was like the tree turned right made a circle then grew straight (not what it did) because the inside of the burl was straight grained like running in a circle. Not an eye, not an onion burl, nothing just straight grain. My first cut on a full circle burl is straight down the middle of the thickest diameter, gives me some idea how deep the burl runs. Hopefully I'll get a couple slabs and two good bowl blanks.
Yea, many of the burls I've seen (not that many) are more lumpy. This seems to have some very smooth areas. It will be interesting to see what's inside.
I cut into a much smaller one (that I could at least roll out into the snow and cut) This one may require my loader to lift off.
