Hey, thanks! Feedback and advice is exactly what I need.

Where did you note lack of rig tension? (or where do you think it hurts the most?) I was surprised to see the forestay curved upwind, I thouhgt the wind itself would keep it straight even if rig tension was a bit loose (per my previous experience), but apparently this jib is big enough to do that. (I am assuming that the jib halyard tension is not intended to take that much tension and help keeping forestay straight). The jib halyard system is currently 1:1, I will modify for more purchase, not sure yet if I'll rig the halyard throuhg the stay or through the mast, I'll try the ideas I have on my mind and see.

I didn't play too much with the traveler car on the mainsheet and not a lot with the downhaul, but I had in my mind that too forward and too tight, respectively, meant 100% de-powering. I hear your advice and will be testing.

Please explain what you mean by "In - column is faster .."

Please more details of the mast plastic bearing. I saw some plastic circles on ebay but never figure out if they were for what you are suggesting of for a diffent mast step.

Thanks again!
Cheers
