Test where you are with the 24 since it is also a good idea to use a bridging plan with the 24 before you embark using it for the ROP.TBH I've been contemplating running a cycle of either ROP or the Jurassic version using clean - long push press/squat - pullup structure if I'm not where I want to be RM wise with the 24kg once I'm done with my current run @20kg.
Did a test session a while ago and found it smoked me pretty quickly, I'm assuming most people who do ROP with push presses don't do the long push press (thruster style) and a clean before each LPP.
