Did you read my posts?

I oppose them for reasons. And I stated those reasons clearly. They are unnecessary overkill for the OP's needs on this build. For an average weight rider, the rims will wear out before double butted spokes will start breaking.

You said there is "No harm." I am simply pointing out that there is harm. A slight weight penalty and a significant cost penalty. If OP had a box full of spokes already handy in the garage, I'd say "sure use them". But since he has to buy them, pay extra for nipples, and the freight, and use a generic length, I thought that pointing out an over $30.00 savings and getting custom lengths would be a worthy post.

What's wrong with my math?

64 spokes at .45 = 28.80
2 boxes of nipples at 2.00 = 4.00
Freight is 19.86
-----------------------------------
Total = 52.66
-----------------------------------
Conversion to USD at 1.16 = $61.09


The difference is enough for OP to build TWO sets of wheels using double butted Sapims, or buy tubes and rim tape for this set.
