During the off season there have been a few powerlifters I know of do HST. When you stall it can be a good way to keep progressive loading.
The problem with jumping straight into something like Westside is you won't take advantage of the linear progression. When you start out training, each time you overload a muscle, if you start light like you should, the nervous system activates more motor units each session. This is commonly referred to as beginner gains or newbie gains. Once you take advantage of that, which will usually be your best gains, you start training for whatever your goal is - Olympic lifting, powerlifting, bodybuilding, etc. but I firmly believe size and strength is not separated by routine preference, but rather principles and nutrition.
Besides, it's not necessarily good to start out doing speed squats like Dynamic Effort day at Westside when you have yet to establish good form, which usually takes a few weeks.
