Might also consider Wave training/Wave loading as an option if wanting to go light (higher reps) and heavy (lowing reps) using the same movement, in the same group of sets. Wave loading has been around for a good amount of years, though mostly for strength training., but also functional for BB'ing.
basic example:
Bench press...taking the average weight of 220 for 8 good reps. Never going to failure. Feel free to apply this same idea to traps or any other exercises. Works very well with squats & DL's.
220....1 X 8
250....1 X 5
220....1 X 8...this will feel much lighter from the first set, but stay with the original 220.
250....1 X 5..may feel a bit taxing
220....1 X 8 or as many reps above 8 that you can....without approaching failure.
May take a couple of workouts to select you starting weights. Everyone is not going to respond the same way. Remembering these are just example weights.
For power....bench again. Never going to failure.
260...1 X 3
285...1 X 1
260...1 X 3
285...1 X 1
260...1 X 3
Some guy's will add weight from set to sets (usually 5lbs, or so), some will stay at the original weights throughout.
Quite a few different approaches to Wave loading, might want to do a search if interested.
Good Luck.
