Haven't experienced anything similar in IDF either. Have any of you gone through same problem? Is it normal? Maybe my rack needs readjustment/ modification, in some way i do not know about? (using Alice pack) Any input appreciated.
I could not find a post with info on my questions, if such exists, please direct me there and delete this post, back to PT.
Thank you.
