Anyone got experience with gas permissible contact lens?

[mrhasan]

Got tired of wearing glasses for the last 18 years and with the new high index poly carbonate lenses, its just a PITA due to distortion. So got an appointment for contact fitting this Saturday and I am looking forward to it. My power is quite high (-6.75 and -7.00) so I was thinking of getting GP instead of more popular soft ones since GP seems to allow more oxygen, less chance of infection and better vision. But the adjustment period seems to be the only concern and all I found was contradicting opinions all across the web (not surprising!). Was wondering whether anyone has any 1st hand experience with GP, even better if GP and softs. Thanks
