I can bend high E from 8th fret up to perfect D but if I look at your picture it seems to me that your bending technique isn't good; how do you bend? with your fingers moving outward or with rigid fingers and turning your wrist? looks to me you use the first way and that is not the good way, like that you may get the issue that the other strings might slip under your bending finger and make some unwanted noises. With the second way you can easily apply more force then when you only bend with the strength of your fingers.

BTW; I have both on my strat and les paul 9's.
