I tried out some new (to me) products while thru-hiking the Long Trail the last few weeks!  We ended up really enjoying Ultima packets, which tasted way too sweet to me at first, but didn't end up too bad when diluted appropriately and served as a candy like boost to help with motivation. I also included Tailwind, which I had wanted to try for running purposes.  This one was key as we were trying to get as many calories daily as possible without lugging too much weight (sadly we both lost more weight than we wanted...).  These were 200 calories a piece and most of the flavors in the variety pack were great!  As for straight salt, I also always use Saltstick tabs and so these came along as well.
