The tapered ring compressors are so nice and easy to use. Broken rings are a thing of the past. Think of it as a cost of building the motor. And a tool you will have for the rest of your life. Including any future rebuilds.

If you do a lot of different size motors/pistons, then the locking pliers type with several bands are the next best thing.
