Aahh-soo, yes what KofK says, build the S/A but don't get rid of the JCH because likely it's a clone in which case it can be used for spare parts for the S/A. Not all are clones but I've been lucky in that the two JCHs I have both have interchangeable parts with my S/A AWs.
Not sure I agree with KofK about the need for washers but every man's mileage does vary. Mebbe I use a different spoke and just have been lucky so far in not needing washers.
