Thanks Brucat for starting this:

I have been rather amazed at the service I got from Spinlock. I was having a problem with using the older style for my downhaul. I sent them in for repair twice. They were right on them and sent them right back. The third time they mentioned that they had some racing version of the same blocks and asked me if I would evaluate them. According to the rep on the phone I was using the equipment properly. Then newer model mounted on the boat without mods and worked great, and still do. All I had to do was to call them and let them know what I thought. They are very attentive to the sailor.

Later,
Dan
