I do high reps all the time
I would consider how I train powerbuilding, but I use high reps sets frequently. reps of 20 and 50 are not uncommon

reps of 50 squats are brutal at the end of a training session
leg presses are a little more safe for those, but doesnt cause as much over all pain

high reps/volume is rotated not for the workout, but rotated within the workout all the time
I may start with reps of 8-10 for 2 to 3 exercises, then transition into supersets with high reps and just challenge myself to got through fatigue and beyond to make sure I am really done

Not that I train instinctively as some would say, but I like to use variety after my major lifts are done, as well as change the order and intensity techniques to force change.

Oh wow i do something kinda the same legs do be dead and pumped to hell even after my warmup set lol good stuff mate
