Take you time with it. You may really like the new line. It will not be as comfortable on your hands but you will get used to that. You can take the blocks off and put them in warm water and a little vinegar over night. Run them under water and spin them. This does a good job of cleaning any accucmulated salt etc out and not creating any problems. If you are going to spend money on blocks think for a while first. I mean a while. If you are going to that expense get exactly what you want.
