Best ifs kit? rms, hdk, gt suspension, or magnum force?

OK OK everyone, this is getting very heated/turning into a big pissing match it seems. I like all the kits out there (except magnum force and control freak), the thing is, yes, there's not a ton out there on gts yet, Carl flat out said that he doesn't have a website (working on it) and he doesn't push his product, if it's really as good as what the few customers I've talked to claim, it won't be long and word will be out, I've dealt with suspensions for many years, and if it weren't for my bad back, and poor vision, I'd be building my own, and after talking to Carl about his product, he answered every question I had, and I knew the answer before I asked, so he is very very knowledgeable, so yes in some ways I'm taking a chance on a new product, but I like to see the guys that pour everything they have into something they believe in, I went through that starting my own business over 30 years ago, I have great respect for everyone on here and I apologize for getting heated earlier, but I'm sure in no time, you'll be hearing a lot more about these setups, I'll be posting pics when I get mine installed.
