A friend of mine got a PLU with red switches, and I tried it very briefly today. The reds definitely feel lighter than the browns, but not substantially so. The relative light feel of the red switch may be partially attributable to the lack of a tactile bump, but I don't really notice the missing bump that much as I feel a difference in activation force. The red is definitely a decent switch, but probably too light for my taste, although fairly close in feel to browns. It is much better than though black switches though, which I hate due to their high activation force.
A little OT for the thread, but I was at his place to temporarily swap brown switch keyboards: my Leo for his Ducky. It's odd, but I definitely feel a difference, with the Ducky feeling bouncier and more responsive. It could be that my Leo is broken in, and his Ducky has hardly been used, as he tends to use blues and an IBM Space Saver most of the time. I'll be using his Ducky for at least a month, so we'll have to compare at that time and see if they feel more similar. Also, no squeaking stabilizers with the Ducky! I guess the point here is that your red switches may end up feeling different in different model keyboards, as well as new vs. broken in.
