So I believe I am getting ready to head down a slippery slope. I currently am running the reference line rf28(l&r) and the 25c for center. I am debating on going up to rp280, and rp450s. So the question is..... is the upgrade going to be that significant??? I have been happy with what I have had so far, and the old statement of ignorance is bliss pops up in my head. I just feel like I’m missing out on something. Has anyone made that leap? Was it substantial? All I ever owned/heard before this was htib shenanigans. Help!!
