Check out the new Gri Gri 2. I've been talking to the distributer and they're saying March 2011. Apparently the lowering mechanism is better. So, after I get my hands on one and test it on our gym ropes (I assume they 'll be awesome) I'll order a load to replace ours. That also means that if you want a cheap Gri Gri we'll be selling about 20 of them for $25 bucks a pop.
