i have been to both. bad branch seems to be the best bet but no fishing. also if you parked at the church you ways along way from the fishable water. there is a trail that goes to hensley's settlement you follow it to get some altitude.
if you want some help i will go with you but, with the ph martins fork and shillalah is probaly dead. with poor fork not far behind. poor fork has alot of garbage in it and gets really low in the summer but all three has good water temps.
here is you another good articule on them both in bell county.
just let me know,i have rested after turkey season and i am ready for another good hike.
