    Hi,
    I have just put the o-rings on my heavy caps on my Carol Brass 5000 YLS. After about 15-20 minutes of testing diferent o-rings tickness, tweeks and alternations between standard caps and heavy caps, I can say that I feel preety big diference in response and intonation in a better way. High notes are even clear now. I am very happyy about this.
    It isn't a very big diference but is noticeble enough.

    Thought I'd quote myself to update this info, since it's 4 years old. After another year or so of experimentation after that post, I settled on a different "heavy cap configuration" which I still maintain. The Bach 184 gets one heavy cap on the 3rd valve for better slotting - any more and the tone is too dull and the upper register is a little more difficult. The Bach 43 gets no heavy caps - it plays more open and trumpet-like without them. The Bach 239 C trumpet gets heavy caps on all three valves - they seem to make the slotting much better (and in tune) and the horn has a rounder tone.

    Sorry, I haven't looked at last post date.
    Anyway it's good for other players to know.

    Below you have the picture with my setup (before and after)
