We approve this comment!I used the CES Neon (Square mains) and the Liquid Neon (hexagonal crosses) with 45 lbs/ 48 lbs as recommended by them. I enjoyed the feel of it. What level player are you and are you looking for more power or control? The poly string does feel a bit on the low powered side for me so the 45/48 worked well. If you have plenty of power, then I would suggest something higher like 50/53 lbs.
