I've had good luck using the 4 pound closed cell. It's a lot easier to sand then the 2 pound closed cell and doesn't "dent" as easy.

Last top I ordered from electron this year took 3 months to get and then they didn't send some parts the well wasn't completely stitched together and the heat seam on the center bow wasn't glued for about 8 inches in the middle. I have switched to Robbins for all my tops now. More expensive but well worth the $.

Thanks everyone now I have multiple ideas. And yes I cet my welt cord at 1 1/4.

I never thought of that. Thanks Adam!
