The ALF was a weaker cover than expected
I had reached out to Mitch Beasley at the time and the advce I was was given
"FOR ME"
was to drill it stronger than you would think, or it would not be strong enough motion
the factory used a clean n sheen polish on it which is a gritty Matte polish, not the normal powerhouse factory finish product they normally use
I had several ALF. I kept the one with a pin under bridge layout and take it to tournaments just in case. Its still a great piece
I have purchased the clean n sheen polish to use as well, but I have had that cover at 1000 dull to 4000 with polish, all with good results
As for the Tundra, I know its a original 300C replacement with a new cover
I haven't thrown it, but from what Ive seen and heard, its a bit stronger than the original ALF
I would take a look at the Nitrous also
Nitrous -

unless you want to go with a Columbia Scout, but its a pancake weight block
