Thank you for a great topic. I found that this is the single biggest pain in the ___ on my 9.1. The jib sheets are constantly hung up on these blocks when tacking. Also, they had double tiered blocks on my boat. I took off the top layer a few years ago. All they did was tear my shorts. I have considered removing them altogether, but thought that the sheeting angle might be bad. Never thought about the overrride possibility. Hate to drill another hole in the deck for the shock cord. Any pictures on how it looks?
