I'm doing high bar. When I try low bar it just feels unfomfortable for me.
Actually, low bar and high bar are not that different as some people tend to think.
Both have some advantages and disadvantages, so its simply a (mind you: small!) tradeoff when choosing between the two. When youre comfortable with one, but not with the other, be it due to former injuries, restrictions etc, just do one variation of the two and youll be fine, especially when training for general strength (whereas you *have* to do low bar squat as a powerlifter and should do high bar (and above: front sqaut) as an olympic weightlifter).
It's always possible that will be chapter 1 of the 4th edition of SS:BBT. Just do whatever feels right/comfortable and you'll be fine. Knowing Rip, I have to guess probably not though, and these are the Starting Strength boards, so I'm going to continue recommending that people who are capable of performing the low bar squat do so.
Honest question: Do you/the lifters you coach (if any) not have to take significant poundage off the bar when switching from low-bar to high-bar? Or are you suggesting that the absolute load doesn't matter?
I'll also note that there are probably quite a few people around here who do quite accurately understand the difference between high bar and low bar squat, based on their extensive lifting and coaching experience coupled with solid analysis. I suspect that you may not have read the book, Marenghi, but I genuinely and honestly recommend it. In addition, here are just a couple articles about the subject that might interest you, or someone else who stumbles across this discussion:
