2. I can anodize it pretty colors...I'll post some pics when the weather warms up and I can crank up my anodizing tanks again.
3. I Like the Al top plate cuz I can mill off a few thousandth's and put "pretty pictures" in the anodization, and if I get really "fancy" I can re-anodize the new exposed metal a diff color, as long as I can find electrical connection.
4. My temps were good enuff for me...I'm not interested in "Rocket Surgery"
5. The fact that I never went beyond 200 grit lapping(if you can call 200 grit lapping) should probably get me even lower temps.

anyways thanks for the post, it made good reading, and I never realized Al vs Cu was a big debate here...

I have made several AL blocks on my mill. I agree with all you said above. I love milling AL and made some very good performing blocks from it. I don't use it anymore though. Copper is just superior. Silver is even better.
