I agree- I don't care for straight leg, or worse, tapered leg (where the leg gets narrow from the knee to the ankle). My boot cuts are usually 9.5" at the leg opening; I like my hems to just barely scrape the ground in back when standing straight, so I usually have them hemmed to 30" exact. I also don't like a lot of shoe/boot/ankle showing when I sit, so the longer inseam also helps in that department as well.
As for rise (that's the measurement from the top of the waist to the crotch), I typically find that 9.5" is about right for me; not too high, but not too low. I have some Diesel X-Rotucks that have a 9" rise and those are maybe a little too low for me. Low rise are good for girls (my wife usually wears 7.5" to 8" rise), but on guys, that is certainly not a good look
