I plan to hike Mt Whitney by June 13. I was told that at that time of the year there might be some snow up there. I never hike with snow clamps. Which one should I buy? I see on ebay some choices...which one should I buy...does it matter ?
Snowclamps...You mean crampons? The Black Diamond Strapon steel are a nice all around model, the Grivel G12s are great and are very solid, but might be overkill for just using them on the switchbacks for a half hour 1x/year. If you're likely to use them several times on other hikes where you might have mixed terrain, definitely stay with Steel vs. aluminum, since aluminum models will dull sooner or even might crack. For once or twice a year on pure snow routes, aluminum have their value in weight savings though are pricey.
Many people use microspikes to save weight. They have their use on moderately easy icy sections or packed snow, but don't bite very deep for those sections where a fall would have bad consequences. Your risk mindset will dictate your choice there. I used these in places like the Bright Angel Trail in Grand Canyon but would not feel comfortable with them on a real mountain, stick with crampons. Also, if you're in terrain where you need traction, you'll want an ice axe. However, make sure you get some instruction/practice on using them.
