Have done giant stride of 6+ feet in doubles with no problem and in singles from 8-10ft with no problem. You don't go under more than about 6 inches if you know what your doing. Usually on the longer drops I have done, we do them as a negative entry due to conditions. I have done some 6-7 foot range though as positive entrys as well and no problems there.
Just make sure you secure all and hold your mask and regulator and know what is under you when you go. BP/W helps a lot where everything is secured and you have a crotch strap.
