Tom,
I dunno – it seems to me like changing the cap or even the slide is a stretch of the term “jetting”. I don’t know who is right, but the fact that you, Doug, TAG Usa and myself have read this rule in different ways indicates this is a grey area. That’s why I asked the question in the first place. I hope that CSC gets a tech “goto” person from whom we can get definitive answers on questions like this.
