you are now talking about chinese ti tubing made tubing vs american made ti tubing. the weld quality won't make much difference if the tubing is suspect. again, on-one stated head and shoulders above. they've changed that after i mentioned to them it was not in good taste but to compare your ti frame from bikesdirect to a moots frame as being as good just with not as aesthetically pleasing welds is a stretch to say the least.
How is that a stretch? Did you ride both? I did. It rides just like any good titanium hardtail with well selected shaped and butted tubeset. Certainly much better then straight gauge tubing that some fancy American makers put out. (Litespeed I have had was certainly worse then Fly)

hard to control the quality of your tubes and welds when the bikes are welded off site. unless van nicholas is x-raying the welds when the bikes hit their shop, they can't tell jack from looking at them and they and their customers are at the mercy of the fabricator in "the far east".
Have you heard reports of them breaking? I did not. Good Taiwan welders are quite good, that's for sure.
If they are welded off site, yes you rely on your source to control. So what? Same story with every other bit of equipment. Look at your bike - where all the critical components had been made? If your chinese made carbon bar brakes are just as screwed as if you Taiwan welded frame cracks.
tell a welder that a weld is a weld.
Once it is good enough - it is good enough. It will not be much stronger just by being a bit more neat. And if you ask - I have been working on experimental physics equipment for quite some time in my life, and fabricated a lot. Yes, I do not know all the bloody details - no they do not matter here.
If the world of BMX frames - large Taiwan shops have far better heat treating equipment then any local builder would have. Not applicable to titanium - but I see no reason whatsoever why they would not be able to make a quality job.
you can't tell the quality of a weld without testing it. looking at it tells you nothing about the penetration or the tube fitment.
Riding it is also testing. Have you heard many reports of say bikesdirect's or Van Nicolas sourced frames breaking any more then boutique ones? If you did not - all the poo-pooing them is nothing more then F.U.D.
Every time one mentions some of those boutique makers, fan-boys come out with all the tales of magic pixie-dust applied to their frames making them indestructible and climbing hills all by itself. Whatever.
