I've posted before how finicky and prone to getting stuck the sweet mead yeast can be at times, which is why I don't use it personally.
US-05 will get you about 12% ABV if it finds your must a good environment to work in. That would put your finished gravity down to near 1.004 if it chews through everything without giving up early, so if you can handle that you can go ahead and pitch it in.
Cheers,
