Rms street lynx vs. back half parallel 4 link

I think it comes down to strength and adjustability. I've witness AbodyJoe's car... It launched very well but there was some tuning left in it at the time and I'm not sure if that system has the adjustability a car like your thinking of may need. Admittedly I'm also not totally familiar with it so take this opinion for what it's worth. If it was me, I'd go 4 link.
