Looking for a single StiX Adjustable Buoyancy Float, either Jumbo or Large. I'm using a TG-5 in a PT-058 housing with a a single 5" ball arm. I was going to buy the entire set but thought I would ask here first to see if anyone had an extra one they were not using and wouldn't mind parting with. Please let me know the price, plus shipping, if you have one. Thanks
