Weapon-R is by far the better fitting pipe of all the intakes. The vaccum hose attachment points are nearly perfectly located. RM vacuum hose points are okay, but the large main one is a little wiered and on the underside of the intake and far away near the filter. As for the TCS issue, the Weapon-R is the only one that actually makes a TCS application, but that is really no big deal. It is just a shorter pipe which you could cut down if you had a NON TCS pipe. Also, the RM even as a NON TCS pipe will still fit the TCS application, but it will be a very tight fit. I've seen it firts hand on a 94 GS Seden with TCS. As for the foam filter, everyone keeps saying it sucks and that it will fall apart. Well, I had mine for well over 3 years, and I know other Legend owners who had them since around 1997. Niether of our filters have fallen apart or show and signs of falling apart. Mine is kind of dirty looking now, but occation cleaing gets it to look a little better. All the filters I've seen and what I have it the V2, so I have no experience with the new Dragon filter though.
