light heart solo? Never heard of them.

Edit. Just checked them out. I like it, except I don't use trekking poles. Down side to me, only a 30 day money back guarantee due to the usual, but needs to be in new condition to be returned. I believe some of the other cottage industry gear makes can beat that guarantee. Not available for sale until May, no pre-orders, but available at the annual PCT kickoff thing here in CA. The thru hikers need it before that to try out I would think. We'll see.
