Blow out water lines question

Well, I chickened out and used the pink stuff. I am considering blowing out the lines again to remove most of the pink since the lines and valves have been flushed. This is in hopes to reduce the amount of effort it takes to remove that pink stuff taste in the spring time. Now that I know the valves and water pump dont have any residual water in them I won't worry.

I'm thinking between the lower amounts of residual pink coating the lines and using baking soda in the spring, it will be easier to remove that taste.

You did the right thing. Simply put blowing out the lines is not 100% foolproof vs. antifreeze.
THe residual water that may remain in the lines will always have the potential to create issues.
However if you run anti freeze through everything there won't be a problem.
I understand lots of people use the blow out method successfully.
Blowing out lines may have a 90% success rate. It may even be 95% successful. However do you want to gamble with the 5% error/failure rate?
Most likely the pex piping will be OK, it's a fitting or fixture that will fail.
Failure will be much harder and more expensive to deal with than 3 jugs of antifreeze.
For me the decision is easy. I don't want any surprises come Spring time. Antifreeze is foolproof
