If this tree is large enough that it needs to be "limbed", then you seriously need to find a Certified B or C Faller. If you do not know what a Certified Faller is, then you really do not have the experience and safety training necessary to drop this tree. I am a Certified A Faller for Wildland Fire Suppresssion and it took three days of classroom and in-field training to pass that testing. The first and foremost thing in your bag of tools is knowing when to walk away. From what you describe I'd look at your tree and I most likely would walk away, It's hard on the ego, but like some of these guys have said, this is dangerous. Until you understand bind, tension, compression, head lean, side lean, safety zones, proper use of wedges, gunning, face cuts, back cuts, relief cuts, corner nipping, and more maybe you should bop down to the local chain saw distributor and see if you can sweet talk a local Faller into dropping your tree. Take along one of your cooler looking bows to show off. From the way it sounds you'll have plenty of staves to make him a bow afterwards.
Jape really said a lot when he advised that you have all the gear, equipment, and experience. I have seen some astounding things happen when highly experienced sawyers were short of gear, but they had what you can never buy, borrow, or fake...experience.
For what it is worth, I have a local tree service that traded me 4 cords of cut and split maple firewood and three 7' sections of bur oak (at least 12 quality staves) in exchange for a hickory board bow and 6 poplar arrows for his kid. Don't underestimate your powers of bartering and don't overestimate your technique as a sawyer.
