hit this on 10/16. solo it took me 6 hours to reach both peaks and return, I didn't stop very often except for the peaks. towards the top, things were a bit icy, and the descent from Giant to RPR was definitely the toughest; I went for a few tumbles. was able to get away without microspikes, but it looks.like those days are numbered. Bring layers, it was mid 50s at the base, but ~5 degrees with wind chill at the top.
