I remember that Scarecrow disclosed some extrusion price information recently and using his data suggests that one can have 34 superwing masts made from a single 500 kg batch costing about the same as 2 carbon masts.

Even when cherry picking the lightest (and straight) 50% of that batch and scrapping the rest will see a builder end up with 17 (light tipweight alu) masts at the cost associated with only 2 carbon masts.

Thus making the alu masts about 8.5 times cheaper then a carbon mast. Falcon marine states 3800 USD for a carbon mast upgrade. Divide that by respectively 17 and 8.5, compare the results and ... ... well I'm not allowed to continue here. But a careful reader can now draw his own conclusions.
