I have an autopilot DIG-220 with a SC-36 cell (5 blade cell). The cell is on the way out and I am going to replace it soon. The SC-36 has kept up with my pool but I run it hard. I have been told by a few sales people that buying a larger cell will extend the life of it as I can run it at a lower %.
My question is: Is there any down side to over sizing the cell? I know some people worry about losing fine control, but I don't know if that will be a problem as the DIG-220 has three power levels from 0-100% each. Being a basically impatient guy it would be nice to raise the FC lever in a hurry if I choose. I am going to either buy the SC-48 (7 blade cell) or SC-60 (13 blade cell), or whatever is the current equivalent model number. I think they have changed the model numbers. What do you guys think, the 48 or the 60?
