Lead is notoriously poor for thermal conductivity, and when figured into the equation, I would GUESS would have a substantial detrimental effect. Just my $.02.

[quote=T A 70;4343966]Yes, agreed. But copper does not have the strength of aluminum therefore larger tubes and dissipates heat better by design...far superior...
and no solder "hot spots"...[/quote]
No, it was mentioned...just fell on deaf ears....
