IMHO you need help. Or new buddies. Do they tell you what car to buy also?

Should quantify that, its AF accuracy has not been as good in Servo Tracking.

AIServo? Relative to my Ls, yes. But on par with my 28 f/1.8, and far better than my 100 f/2.8 Macro.

Erm, you really want to put a Macro lens in this mix

Why not? Surely focus tracking is just as important for macro.

No, it's not.

The MACRO lens has its elements arranged for close focus with adjusting lenses that have to move comparatively great distances.

The wide aperture 300mm 2.8 is especially designed to reduce lens cluster travel, specifically to enhance AF and AF tracking speeds.

I'd expect the 100mm Macro to track badly, in fact I'd expect the 70~300 cheapo to out track it easily ~ and that lens can't track for nuts.

As a MACRO lens the Canon 100mm is the fastest in the business when used as a MACRO lens, as a portrait lens, mine anyway, is noticeably slower than either 50mm {1.4/1.8] but it is adequate and sharper.

I must actually try mine for tracking, just for pig-iron, it moves from object to object fine and dandy but I've not tried my boxers or basketball with it ~ I'd suspect it would be disastrous, in servo mode.

I was speaking of using AI Servo for macro. For any kind of action with the 100, you'll need to develop MF skills.

Well now, I really must ask you to explain that one.

Do you follow bees around and the like?

I don't shoot bees. Macro is much more diverse than just bugs. AI Servo can help compensate for slight back and forth camera movement, especially when using some vertical support, like a monopod.

This very close to 1:1

Gotcha.

I can see how that would work, must add this to my tips bags and give it a try.
