thanks for the responses. i guess whether a such a spot closes out or not depends partially on the angle of the swell, as well as how the sand bars are sitting at the time, and maybe on the swell size, and, if so, i wonder what swell angle and size may work best these days at frisco.
It's kinda like anywhere else on the east coast. one spot could be peeling like a bananna with 50 guys on one point, and 50 yards down it could close out completely, and 50 yards from that, it will peel again with 10 guys on it. If there is significant swell, it closes out much more on low tide than incoming or outgoing. The bar is pretty far out at some spots. It completely depends on the swell.
