What skill should i do over double exp weekend in runescape?

Heey guys. if u dont know this already, double exp weekend is coming up on runescape and i really wanna take this as an opportunity to get a skill up high.. the problem is idk which one..-.- as of right now im attempting to get 99 fletching, cuz its easy and i know how to actually make money off of it. but i started to think maybe i should take advantage of this opportunity and get up a skill that could make me some nice hard cash. the skills that i had in mind were Woodcutting, crafting, or just sticking to fletching. My current levels in these skills are Woodcutting:74 Craft:55 Fletch:77.. kk soo let me know what u guys think, either vote out of these 3 or just gimme another suggestion, and id also like the skill to be fairly enjoyable or laid backk.. OH and by the way i am a member, kkkk thankyouu!
