Maybe a good idea to check the existing threads on the builds of these frames?

Yes of course and I have done that.

There is not much info here or MTBR. They show the build, but there is no commentary or feedback of the frame with some actual miles on it. I found one, but it just spoke of some creaking which ended up being the cassette.

I would like to hear about the durability with some time on it.

I'm currently on a Yeti 4.5 but looking for a bigger travel bike to better suit what I ride, and don't feel like spending $3600 on a frame.

I like nearly everything I see in terms of geo and specs for the Light Carbon 713 which looks to be identical to the TanTan FM08 as well.

How many people out there are riding them hard? Or at all? I'm not seeing much info on them.

I plan to build mine with a Fox 36 at 160mm with 44mm offset and probably DPX2 at 141mm. Maybe 150.

I ride rough, rocky terrain (mostly) - I'd love to hear some user feedback - how has it held up? Does it handle rough terrain well?

Any input would be great. Thanks.
