Curious as to why you would "hate" a slipper clutch? Generally, if you know how to ride and are just cruising, you never even know that the machine has a slipper clutch. We run them on our race ATVs for a totally different purpose and have seen no real drawbacks, only advantages.
Yes they have their purpose for racing and allow you to keep traction with sloppy downshifts, but I personally have no use for them. I highly doubt that anyone buying these half-ton luxury touring bikes are going to race around a track all day. I also find them just another unnecessary wear item ... in the long haul, extra wear on clutch discs and in time I bet the ramps can possibly wear or develop nicks which hamper it's function.
As to why I hate them ... The only bike I ever experienced a slipper clutch was on a 2013 K1600GTL and it's traits completely ruined the feel of an otherwise excellent bike. Around town keeping pace with slower traffic where you constantly are on/off the throttle ever so slightly, you are treated with an audible clack, clunk whatever you want to call it every single time you load/unload the drivetrain, no matter how smooth or gentle you were with the throttle. I found it very irritating and could never put up with it on such a nice bike so I passed on it. If that bike had a standard clutch I would probably still own it today and someone else would have got my Ultra.
I'm sure older people with less hand strength also love the lighter pull of the assist part of it, but at this time I have no use for that either ... maybe someday, but not now. You are right, under normal cruising you may not even know it's there unless it gives you that sloppy, clunky feel that the GTL did that I rode and again ... I could not put up with it. I want my putts through small towns as smooth as my highway jaunts so ... If I can physically feel it, it's a no go for me.
