Hydeyongsungs ... I'm not sure that's true, I just ordered R2TLS-USV-IV tonight which is both variable weighted and silent (the new R2 TLK model, ivory color). Last week I bought the 45g APC limited edition (also silent) which I love, but since I type all day, I really need the 30 grams for my pinkys so that they don't get sore (I'm 60 this year so it's more of an issue).
What I really want (that's not offered) is an ivory silent variable weighted APC TLK board. Then I'd have everything. If my 45 gram keys get tiring after too much typing, I could just raise the actuation point for those keys to 1.2 mm. And, if certain pinky keys are to easily actuated with the 30g weight, I could lower the actuation point. That would be just awesome. But of course, you almost never get everything you want in one package. That's OK though because it just makes you appreciate each keyboard for it's good points.
