The SLT sounds like the action you are looking for for the waters you stalk. I have an SLT 590-4, XP 590-4 and a Z-Axis 690-4. I find for smaller waters, pools and casting distance of 40 feet or less that the SLT works best (for me) having a softer tip. I recently bought the 490-4 ZXL and like the action, especially in the 10'-30' range. If you can, try the ZXL.

Keep us posted on what you decided on.
