? I have never heard this. All I do is fish salt, all I have is the spools with holes cause they cast a whole lot better, but I have never had a problem with several curados (green)and recently a citica 100 that I swapped the spool out from a 50mg. What should I be looking for as far as problems? I use them alot and im out wade fishing with them, just wash them off when im done and no problems so far.
It can allow water to enter the reel through the holes in the spool. Place a piece of masking tape over the holes and you will have no problems. If you properly maintain your reel then you will see no adverse effects from having a Lo-Mass spool.
