To be honnest do what ever you feel like doing!
The odd drop set or ascending pyramid (reps decrease as weight increases) can work very well. It'll also give you a chance to play with some heavier weights without focusing purely on strength training.
Strength training on the whole tends to be much lower volume anything from 3-6 reps maybe 4-6 sets with a much heavier load usually 80-85% plus of 1RM. Sometimes even 110-120% of 1RM when perforing negatives but these are very advanced. Ploymetrics (explosive movements) are often a part of it.
Volume also tends to be much lower as does intensity. You will rest for around 2-3 minutes to allow the energy system responsible for strength (creatine phosphate) to replenish
For example if you normally bench say 40KG for 10 reps and require 90 seconds rest you won't be able to bench more weight with the same amount of rest between. It takes more out of you, short term between sets, and also long term for the body to recover.
