I am revisiting our opening leads agreement and seek guidance on some ideas I have come across that sound like improvements.
This post is to seek a second opinion and, if the change is positive, seek a bit of guidance.
I think I know the answers to my questions, but having a forum like this to get confirmation (or correction) is a boon.

1. When declarer or dummy leads we currently do not signal at all.
Proposed: Give count. Assuming we do not try to win the trick, playing high suggests an even holding, low suggests an odd holding?

If we do agree to give count, and we hold 4 small, which one do we play first? Highest we can spare? Which one do we play second? Lowest? How does partner know it is 2 or 4?

2. Leading our own suit, we currently lead top down ie A from AK, K from KQ and partner always signals attitude (unless dummy is void or solid).
Proposed:Lead of K asks for count and lead of A or Q asks for attitude?
So does lead of a top honor no longer promise the next lower one?

3. After seeking advice on this forum, we are preparing to change how we lead partner’s bid suit. We are going to give count if we did not support their suit ie show we have an even number by leading a high one and if we have an odd number we lead low.
Just to be clear let me ask: if we have an even number, with or without an honor: we will lead the top? If we have 3, with or without an honor: we will lead the lowest?
Against 3NT, should we still lead low from 3 to an honor?

Thanks

1. Giving count is a common and solid agreement. I've played other agreements in the past (such as suit preference or Oddball/Smith). I think distribution is fine, and a good habit to get into as it helps you and partner develop skills on counting the hand. You may at some future point want to change this agreement. Personally I play upside down count, so that low = even, but your agreement is completely fine as well.
From a four card suit you play the highest you can spare, followed by a lower card. This is easiest to read. You can default to your lowest card the second round - this helps partner count out the hand (again). Alternatively, some people assign special meaning depending on their choice of second card (e.g. suit preference), but this is more difficult to read.
Normally you have a decent idea on the bidding whether partner has four or two cards in a suit. If not, there is no immediate way to resolve this ambiguity. You'll just have to try to figure out what to do in either case, and then take your best guess.

2. I like 'Ace attitude, king count', though there's plenty of other agreements as well. To me the main advantage is that you get flexibility on which card to lead with AK(xxx) holdings - sometimes certain information is more important, and you gain flexibility. With this agreement the king does not deny the ace nor promise the queen - this can be confusing for partner, but since they obediently signal count anyway they only have to figure out how to handle it on the next trick. Other people prefer to stick to 'top of connected honours' in combination with some coded ace/king agreement.
For me the queen does ask attitude, but I do not lead it from KQ(xxx) even if I want an attitude signal. This is a cost of my signaling agreements. In return, my queen leads deny the king. You can change this around - I'm not sure what's best.

3. I don't know what 'give count on lead' is, sorry.

Nice and clear - thank you.
I have edited question 3.
