I have been cooking salmon direct with alder chunks for smoke. Very good. I have tried cedar planks but don't like the cedar flavor. Last night I used alder planks, raging river, a little maple syrup and alder chunks for smoke. The combo of alder plank and alder smoke is the best I have done. Had dinner guests and thought I cooked too much salmon but everyone went for seconds and thirds. Just wanted to pass this along.
