The only problem with this is to be able to recognize 'chop' when you need to. After the fact this is not difficult but it is of no use anymore. Trying to link time frames to chop, imagined or real, may be a poor strategy.Quote from easyrider:

My 2 cents: the only time I drop down to the smaller timeframe is when things are moving very fast. During chop the worst thing you can do, imo, is go to a smaller timeframe. In your situation I would avoid trading chop altogether.
