LR - Q's 20 and up tend to be more diffcult and wordy (ie. verbose) and for LG - Q's 3/4 tend to be a bit more challenging (I know, this isn't absolute... but just my opinion).
Having said that, any potential risks to doing it from the bottom up? I'm thinking perhaps wasting too much time on a Q, where as I should get the easier ones out of the way first?
