Cheers for the input everyone. I have bought some braid from ebay. Its called Super power Spider. Its 0.37mm diameter.
I will be using the rod and reel for spoding, not to massive distances. But I will also be using it for my new fishspy which was bought for me last week. As you will know these are not cheap so I dont want to chance loosing it. Hence the 50lb braid.
Cheers Guys
