Hi mate
Both sound great, and would work well, ir depends on what the vocals are doing.
GTB's idea is good, I would probably lean toward something similar. I would ensure the groove is landed for a couple of bars with version 2, then throw version one in to keep the groove developing.
I.e. Three sets of version two, followed by one set of version one.
However lay it down with the vocal recorded, and that may help!
Cheers
