I would highly recommend using kevlar string for pulling yourself up. My team used it for a pulley slide system for velocity vortex and it worked like a charm. The string was under a ton of pressure but we never had any issues with it snapping or getting damaged.
If you do decide to go with kevlar string(once again, I highly recommend it), you really need to make sure that your spool is very strong(especially if it's 3d printed) and that its connection to the motor is really good. Otherwise, your spool will deform and will probably end up breaking. Also, if the connection between the spool and the motor is weak, the points of contact will probably get damaged by the constant force/torque placed on the spool and your robot's performance will significantly decrease as a result.
If your spool is a solid piece of metal, you don't have to worry as much about pressure being placed on the spool. However, if it's 3d printed(as it most likely will be), you will have to consider the things that I talked about above.

If I remember correctly, we used this exact product and it worked really well.
