In packed snow conditions with crampons you might be temped to cut that last long switch back near the peak and head straight up. I would strongly suggest you try and stay with the trail.
There are a lot of big boulders under that snow, and that area is really steep. If I was going at this time I’d take crampons for sure. And if the snow was too deep / not packed enough that I was post holing – I’d just call it a nice trip right there.
Walking that steep last mile in crampons is not too hard or dangerous. Walking it in snow shoes is a bit more difficult, plus shoes are more work and weight to pack in. A lot of places will not rent you crampons/shoes unless your boots are full shanked with toe & heal lugs. If the rental places turn you away
Campmore has a selection of them. The cheap ones start at $90. They have clearance sales in the summer too.
I usually stash the packs off the trail someplace around Welmans divide, and then daypack it to the peak. The trail from Welmans is above the tree line and you see for miles. Good luck the weather looks bad this weekend.
You know just snow camping in Round Valley is fun too…
