I always use slip floats on ultra lights. I use the skinniest bobber for less resistance. They are also weighted. You can add more weight to adjust the bouyancy of the bobber. If your talking of shallow water I'm guessing your going to fish the spawn, and in that case the bite may be a little more aggressive. So the adjustment may not be needed. The bobber stops I use are in my opinion the best. They are similar to the bone shaped, tiny plastic ones. They have four holes. I typically use three holes threading in and out(not around because as you slide the stop it will twist the line). I Do not use the beads that come with them, they are not necessary. Hope this helps.
This only my opinion, but nothing you can say will change my mind. That makes it a FACT.
Today is a Blessed Day and a Prosperous Day
