I just took a first-timer out in his new-to-him 2019 4Runner TRD Off-road. We did Fins N Things and Hell's Revenge back-to-back and he only scared me once and probably himself several times. I did the same trails shortly after picking up my 2018 JLUR and as much as I want to try other trails, I just never have anyone experienced with me, so I stick to what I know and it's still a really good time!
I remember doing Kane Creek with my family many years ago and have wanted to go back and try it, but I keep hearing it's a lot more difficult now. Poison Spider and Top of the World are on my list for next time I'm down there though!
