Hi all. I have been in this sport/hobby for few years but most of the time I only ride in my HT to tarmac ascend/descend and rocky garden. My end goal is to eventually able to go full DH if possible, so for now I am planning to move on to trail riding or AM.

Now, I have a few questions:
1. What kind of skill I need to acquire before going to trial riding? (asking this because saw people doing jumps and air)

2. Say if I really need more advance control over my bike like manual, bhop, is it alright to learn online or better to get a coach?

3. If I were to buy a fullsus, with the budget of 6k, what brand and model I can get or it is better to build myself?

Thanks in advance.
