i won't comment as to what i would lead - it's not tricky to get hands right having seen all 4 of them but in general i very rarely lead passively when opps have a 6 card suit which looks like running based on my holding. xx of clubs over is about as bad a holding as it's possible to get.

Some people led way too agressive if you look at replies (♠A and ♠ T leads

Those leads are inspired by the fact that this question was asked.

An attacking lead seems normal to me since I expect opps having a running ♣ suit, and a small ♠ is the normal thing to do. Bringing in 4 ♠ + ♦A defeats the contract, hoping for 4 ♦ tricks + ♠A is an alternative but looks less appealing to me. Starting passively with a ♥ or ♣ is probably never right.

If you have seen what a "stopper" looks like in most of
these forum problems a lead of a low spade looks better
and better.

I think you and i have different views about "aggressive leads" or in your terms "attacking leads" To me there are 3 kinds of leads;

-Normal lead
-Passive lead
-Aggressive lead

Aggressive leads are unusual leads for me, such as leading from AQx (A and then Q or starting with Q) in NT is an aggressive lead for me, You do that when you are scared that opponents are likely to make enough tricks in their contract unless we take our tricks first. In this context small lead from ATxx is a normal lead, high ♥ lead is passive and ♦ A lead would be aggressive (or ♠ A)

You have a good point.

Thinking about this problem again, I really like Phil King's ♦A lead. There are essentially two ways to beat this:

• Cash 5 tricks
  
• Partner has a club stopper, and we can set up four tricks for us.

♦A seems to give us the best possible shot at the first possibility, and it's hard to construct losing layouts for the second possibility.
I bet bluecalm's simulation would look differently if he specified 6+clubs for opener (which is much closer to the truth of course).
