You can order a Jacoby Edge Hybrid direct from Jacoby up to 32 inches long with whatever tip diameter you wish. They will custom make it for you. Jacoby Edge Hybrid is a 64 piece spliced LD shaft. They are pricey and it will take quite a long time to get it to you. You can also order McDermot I-2 in 30 inch as well as OB and Preditor shafts just check ebay and search 3/8 x 10 shaft. I assume you are looking for a used one so you can save some money over new price.
Hope this info helps!
