I was greatly influenced by "The Green Brick" and later Tim's Valiant in my build. It's not nearly as capable, but it's still a blast. Too bad we don't have a usable track here.
I also had a dilemma with trim, which I would prefer to keep. I have all the trim but one piece was flat sided, So I just ordered some 3M peel and stick to cover the holes until I can find the piece I'm looking for. Might be an option for you.
Congrats on your purchase! -pauly
