I have the Vedder series Lamiglas (8-12 lb. rating) and I love it. A friend has the Loomis and it is a fine rod also. I think the biggest difference is the action. For a float rod I think the Loomis is too fast an action, and is more difficult to cast a float set-up. The Lamiglas is more of a medium action designed to cast a float rig.
For a dedicated float rod, I would go with the Lamiglas. If you plan to also use it as a drift rod a lot of the time, then I might consider the Loomis.
