Day hiker here... but recently hiked Mt Whitney in a day. For those not on the west coast it is the highest peak on the contiguous US. Its a 22 mile round trip hike which goes from 8000 to 14505 ft. I carried a pack that included a Tops Bob, a pretty stout knife. less than half way up I was cursing every ounce I had in my pack. Looking back I would have packed my More light my fire just in case and a SAK would have done everything I needed. I agree with what others have said about the White River Backpacker being an excellent lightweight option.
Very sensible choices. That has been my experience with larger fixed blades as well. They are more clumsy to use as compared to a folder on light cutting and that sort of cutting dominates overall. Tis why I have the White River Backpacker Pro now and a number of other smaller fixed blades. But still, they don't see much use at all and I tend to always reach in my pocket for a knife when I need one. To force much use, I would have to leave the folder at home and I hesitate to do that.It depends on my aim for the trip.
If it is long distance and camp time is reduced to setting the tent and falling asleep, then I would probably take my SAK Huntsman next time.
Last time I took a long trip, I brought a fairly heavy fixed blade, and it didn't see as much as one second of use during the trip, which lasted 8 days.
If on a trip, where the miles per day are few, and the camp time is longer, then I wouldn't mind bringing heavier cutting tools.
