Progression will be much slower on 5/3/1. Do 5x5 or one of the intermediate 5x5 programs (Texas Method or Madcow) if recovery is an issue on SL 5x5.
Also, pick a goal and stick to it. You're not going to do much if you're trying to build muscle and strength while cutting fat at the same time. Lowering your BF percentage should probably be a priority right now as it's quite high (very hypocritical of me to say as my BF is too high at the moment but I wish I'd sorted it sooner rather than later).
