Kyle,
As Longhunter mentioned, that cooking tent is very good idea in bear country, and if you are not doing thr "ronnyvuo" thing use whatever works. One advantage of the tipi, your fire is inside, and usually always going when you are "home". With a one pole, you can have a tent stove inside and a rain fly outside for cooking, etc. With a one pole, you do have to be sure it is square when you set the corners, minor math AxA + BxB= CxC. Remember too that canvas stretches with age, and does need some care.
