Crampons?
Since snow/ice conditions change daily, crampons would probably be a good idea regardless of where you go. If your snowshoe crampons are fairly aggressive, you should be able to handle most trail situations. However, there may be some sections (steep or icy or both) that may be less hazardous as a result of switching to 10-point crampons. Having them with you at all times at least gives you that option.
We hiked Adams last July in prep for a Presidential Traverse and were impressed with the steepness of the upper reaches. I have included an excerpt from my journal to emphasize this point.
"The first section of the Mt. Adams Trail is a gradual and pleasant walk on a very soft trail. About a mile and a half into the hike, the trail reaches a rocky section and begins a more serious ascent on steeper grades. There are several switchbacks and brief plateaus that help lessen the severity of the ascent. At approximately 1.9 miles from the trailhead parking, there is a long side hill traverse that swings left following the narrow rocky section and ends in an area of significant blow down that has been cut and cleared. This marks the beginning of the last half-mile of steep hiking before the summit is reached. We were impressed with the pitch of the upper slopes. The horizon was low ahead of us and also on both sides emphasizing the sharp angle of ascent and deceiving us to think that the summit was imminent. It was, but not without some additional work."
"This would be an outstanding fall hike or winter snowshoe trip. We were both impressed with the physical challenge of this route as well as the peace and solitude of this remote area. The tower is necessary for the views, but the mountain can stand on its own for an enjoyable and challenging day hike."
If you are prepared for the unexpected, you won't have to alter plans or compromise personal safety. The extra weight of crampons is a small "price" to pay for getting there (and back) safely.
