issues with track... please help!

[Herc Driver]

Take a deep breath and give yourself a pat on the back for figuring out the problem areas, developing a plan on how to fix it, and having the desire to build it again. It's a pain to do the rework, but I'd bet you'll be happier with the changes you make to your future design. Seems like every time I rework a place, I like the end result better than what was replaced.
