Not a mtb, but road bike here.
I owned once a Sekai GT2700 hi ten frame I commuted for one season and the feel was heavy.
Then I got a Centurion ProTour15 in cromo tange 2, that I like much more.
I also have the tange 1 Nishiki Tri-A modified to fit wider tires and all bosses added for fender and racks. It has better ride than the Centurion, for me.
Last year, I tried a Ti Litespeed with carbon fork that would weight around 3 pounds less than Tri-A, but it is jus not there for riding, you know something missing.
Currently happy with the tange 1 frame that fits 700x32c
