I have a lugged Schwinn Frontier that rides very nicely.
I can't tell you anything about the High-Sierra, but I bought my bike to flip but ended up making the mistake of riding it in the parking lot and fell in love with it. It's too small, but it's my go-anywhere bike. I don't do any technical Mtn bike riding, but I would have no hesitation taking this bike out on trails & two-tracks. Here's another pic to give you an example of what punishment I inflict on this bike just by being 6' 4" & 285-ish lbs in this pic from a year ago.
