For general purpose probing why would I choose the P6810 over the P6960 with the optional general purpose leadset?

The P6960 probe can serve well as a general purpose probe with the optional leadset but it’s important to note that any flying leadset will restrict bandwidth because of the added additional loading. While the P6810 can be used with leadsets as well, you have the option of connecting a header directly onto square pins mounted on the board under test. The bandwidth of the probe is not compromised when used this way. The P6810 also has differential capability while the P6960 with the optional leadset does not.
