You may aswell do Yews for FMing, otherwise you are training the same as every other level 90 out there. Atleast beast it to 92 FM with yews/magics, get adze, and do some wc training if you wanna save some money. With the RCing, Abyssal Titan is not worth it unforunately, the xp gained and money saves just doesn't justify the time to mine the essence, believe me, I tried. This - /maybe try filling up pack yaks with granite then dismissing, no dropping involved and supposedly around 45-50k xp/hr
