Hi there-
It's best to first understand why a breast needs lifting in the first place- pregnancy, breast feeding, the aging process, gravity, and weight loss/gain cycles all contribute to the stretching of the breast skin and tissues that results in a sagging breast appearance.
Because these stretching forces occur in 3 dimensions, any technique that does not address all 3 dimensions in a well-balanced fashion will result in a funny looking breast...
So, as I sometimes ask my patients, if I asked you how you would feel about your surgery is you got the scar (technique) you wanted, but your breasts were funny looking? Probably not very good...
Furthermore, while most patient's scar concerns are greatest for the vertical portion of the scar (hence the desire to avoid the vertical scar), most experienced plastic surgeons would tell you that the vertical limb of the scar is usually the part that heals the best- with the least visibility.
Take a look:
