We started using climbers as lock-ons 2 years ago. We wait until walmart/rural king has a sale on their steel climbers. They cost about 70 bucks but are really comfortable. They are more comfortable than most lock ons I've used. We also use the climbing sticks with them. It has worked great so far. I personally wouldn't leave a 200$$+ climber hanging for very long.

good luck
