I pour those with #1 in 1/16 and 1/0 or 2/0 in the 1/8. Had to take a Dremel and small bit and modify mold for sickle hooks. I know those are bigger hooks than most use but we got big fish down here
I have seen on the web site or in the Do-It catalog where it says their molds will accept the sickle hooks. Maybe if you were using the size the mold calls for they might work in the newer molds. I know FatMan sits down and hand fits each hook into his molds before even starting to pour. Also the last couple of batches of hooks I got do seem to fit better than the earlier ones did.
