Wow this is apparently a lot more complicated than I thought! I would say:
Trail - anything that has been designed for MTBs. The colour or grading is largely irrelevant.
Possible exceptions:
Jump line
Bike park (could still be full of trails!)
Ft William? Is the DH World Cup track a trail...
Without wishing to be patronising, it sounds like your issues are much more connected with your riding than with your geo or bike set up. Working on the fundamentals of body position will yield far more results that tweaking bar angles. I think it's important to recognise that not all things can...
Perhaps you are riding a bit far off the back of the bike on the steeps, which in turn is reducing your front grip. If you're then using a lot of front brake because it's really steep, then it could be easier to lock the front wheel. All of which could be exacerbated by having a slacker than...
As above, your wheel should definitely fit the fork. As the torque caps are bigger than regular, the receiver on the fork is commensurately larger. This means fitting a wheel without torque caps may require a bit of fiddling to get it to line up, but it will definitely fit. On rs forks I've had...
J-Tech have always been really helpful for me. They appear to have a new, more detailed spring calculator.

A progressive or not spring will depend on the kinematics of your frame I think.
When I had Code RSC I did this regularly as it was the only way to keep them feeling nice. Not something I have done often with other brakes unless they are disgusting. With the Codes, I used a little 3d printed template my friend lent me. It allows you to expend 1 piston out at a time...
I am sending the 38 Performance from my Decoy in for warranty due to a creaking CSU. It just so happens I have recently bought a Factory 38. I went to swap the two forks, but I cannot get the Factory fork to sit properly. When I tighten up the head cap, the fork becomes extremely stiff in the...
Not really sure why there are so many special gadgets in use. I use a super cheapo, Lidl special bike. It holds my Decoy just fine. It does have 4 legs though. I clamp all my bikes by seatpost, never had any issue. However, for general maintenance, I mostly use a wheel stand. For chains /...
