fish it like you would a bigger rod. you just have to downsize your flies. you could use 0x if desired, but most of the UL fellows like 3-4x like I stated in my first post.
honestly people could pick and nag about UL rods, so I think I will start to pick and nag about guys using bigger rods and 6-7x tippet.(note: markf, this part of my post is not directed at you)
