Thank you, @GeneR, for a neat challenge.  It helped me to practice Predictive tools that I am just starting to learn.

Lot of solutions didn't seem to have considered multi-collinearity in predictor variables (top 10)

for instance R and R_G are highly co-related although they both are significant. It makes sense to use only 1 f these variables to avoid multi-collinearity issue. Similarly, it makes sense to remove 'PA' as well for the same reason.

Had to peek to the solution... Interesting to see how different models behave!

Isn't it necessary to normalize the variables before applying a model?

Very hard as first approach to predictive tools, but a great GREAT training!
