I don't really know why people are so negative about TGS, i suppose it's just your view on it so i'll tell you my view. I think natural is aload of shit, and i like TGS personally.
With my Dob because i had soo much un-used axle as there 110mm i got a 14mm nut and grinded it down to about 4mm and slotted it in. Not that info was any use to you but i thought you might of liked to know.
There's no point really arguing over whats better, its ovbiously down to what you like, i wouldn't trust an ACS where Otacon does, and i would happily try out the new Echo freewheel where Otacon doesn't..
