I still maintain you should try out some rings...might take a bit of getting used to, but the stabilising muscles you work should benefit you well in BJJ..I don't think you should have any issues getting to them right away, and even if you can't do an awesome routine from start pull ups into muscle ups into holding top position and dips is would work out really well..then agaim I don't really work out with a set weight in mind so I don't know if you'll reach your target...they are by far the best bodyweight exercises in my view though.
