Its been a while since I used a 531 program and have been getting into bad habits with training (no real plan or specific goals in place) recently so want to get back to something straightforward i can commit to and use for a meet coming up in 15 weeks.
This is what I’ve got so far and would appreciate some feedback on it.
Using 85% TM: 2 cycles of 5s PRO followed by FSL 3-5x5. I’ll do jumps/ throws before my main lifts (never tried this before but seen it recommended on this forum). This is what i have planned for assistance:

The last 8 weeks i will do the pre meet training the meet prep training as set out in 531 for Powerlifting.
Due to sciatic pain that flares up especially badly after deadlifts (and affects my next deadlift session) i am planning on deadlifting every other week and switching in probably box squats on the weeks i don’t DL and some very light pulls to work on form.
Main questions i have are:
Do the 531 variations I’ve selected make sense heading into a meet?
Does assistance look reasonable/ should i keep similar level of assistance in final 8 weeks?
Good idea to drop to DLs once every 2 weeks, should i increase back to every week closer to meet date?
