A 10ft is a lekker length for surf casting, its not to heavy so you can cast for a long time and very good distance can be reached if you get the hang of it.
I have the penn battle, a very nice reel, but the 8000 is definitely to big paired with a 10ft, look at the 5000 or 6000. You will be able to get 300m of braid on, which I think is more than enough.
