In any event, it seems that my forestay is a little bit shorter than yours (presumably this is a European vs US thing).
The change that occurred is that the mast base became higher causing the forestay to be a little tight. I had to fight with mine initially to even get the forestay to the first hole. Talked to Matt because I know Robi's and Matt's are around 1 on the staymasters and I could get to maybe 7, so I knew something was different. Matt exchanged my forestay for a longer one and now I'm around the middle hole on the forestay and 4 on the staymasters. I'm carrying a lot of mast rake with the trapeze going 6 inches down the back of the transom. The boat feels good with very little weather helm. I did rake one of the rudders more forward to match the other. If I ever want to rake them back, I'll just glue in a piece of rubber. Also, my clew of my main must be cut higher as I have quick releases on both ends of the mainsheet blocks and I have yet to go block to block.
