I just replaced my Mainsheet system last weekend from the original Seaway blocks that measured about 18" center to center when pulled in block to block with

44 feet of Maffioli Swiftcord 9MM

and

one each

And

which measures about 6" Center to Center when block to block

I can not stress how much better these blocks are, and the sheet is awsome as well. The whole system is a bit expensive, but very much worth the money.

Thanks to everybody that gave input on the MainSheet Blocks thread a few weeks ago.
