We're currently running a mini-CIM geared 50:1 for our climber (1.125'' drum diameter), and a 50 amp current limit has worked just fine for us. You can probably figure out a ballpark estimate by scaling appropriately to your system.
If you're using a Talon SRX, you can implement a current cap that the motor controller will not exceed - else, you can program the motor to shut off entirely if the current limit is exceeded. We do the latter, but also have releasing and re-pressing the climb button restart the climber.
