I used (2) bullet blocks that came with the used mast that I purchased. I then changed them to (2) Harken 092 Cheek Blocks. I chose the larger size because the minimal size block will allow the rope to past but can give some resistance. I also purchased a Harken 226 double bullet block. I tried the Ronstan RF5101small V-Cleat with becket, but I found it to be too small for the 1/4″ rope. I changed it to the intermediate RF5106. It worked much better. This system is still too hard for my daughter to pull up the CB from crew position.
