This looks fun - I typically do Marvin or Manhandler but def going to ride this next. Climbing trail is so tough (IMBY) - feels a lot longer than it is LOL.
It's super fun. IMBY is tough for sure but all the upper climbing trails have had a lot of work. A few times I've parked at the Powerline Road gate off of Eagle Mountain Drive, it connects right onto the fire road so you don't have to do IMBY. I think Fortis might be doing construction in that area currently though
The thing to do with IMBY is just to commit walking it without trying to bike. Saves you a ton of energy, and according to my strava it's only like 2-3 minutes longer than if you try to ride, but you end up a lot fresher at the top
