First up I think some of my previous posts have been harshly worded, I don't believe you are incompetent, stupid, reckless or anything like that and I would much rather someone voice their opinion if they feel there is a potential safety hazard, and what you are saying does absolutely have merit to it. The thing I'm not as comfortable with is your decision to unilaterally change an accepted procedure.
There is a method to raise this and have changing it investigated. My question to you is if, hypothetically, you succeeded getting it changed and AIP updated, would you expect other pilots to comply with the new procedure? I would comply if it was written in AIP even though I disagree with you on this occasion. It's asking a lot to expect other pilots to respect the rules that you are knowingly ignoring on this occasion, even if it is well intentioned.
If you feel as strongly as I believe you do about this, then I recommend going through the correct channels and having the procedure changed, until then please respect your fellow pilots, and the professional image of the entire organisation, and comply with the rules.
