I reckon it's a good trade but 3 trades left this far out is a risk. You would want to hold off any trades for at least 3 or 4 more weeks after that...
Only if this week is a must win match. Note: Beams is falling in price. Pearce's next month (Melb, GWS, Port). Should score well. Maybe in a couple of weeks you could do Pearce-->Beams instead. Later on in the season so if any surprises come up between now and then you won't regret a trade this week...
