As far as ease of strip removal it just all depends how they are put on. Some are glued to the reel edges and where they join. Some are just double sided taped where they join. I have one reel I am not sure what they used at the seam but I am pretty sure I will never get it apart without damaging the strip. Take a look at yours and see what you are up against. Hopefully with some patience and care you can make the change easily.
They are easy to put on once you have the old ones off.
By the way, I am looking for a set of Diamond Spinner reels or reel strips. Let me know if you would like to sell yours.
