There are 3 different tines offered, the shatter tine, sports tine and the fine tine (large, medium and small if you will). We use the fine tine on greens, switch between the sports tine and fine tine on tees and switch between the sports tine and shatter tine on the fairways/rough.
The shatter tine hole is visible for probably up to 2 weeks or so. Sports tine maybe a week to 10 days. I feel all the tines loosen the soil below the turf so although the scar from the tine may be healed, the effects of aerating the soil last longer than that. The aerating effect is more than what you would get from traditional slicing blades, no matter which size tines you use.
The Aerway is the only aerifier we use on our fairways, and it works pretty well for us. We alternate between the Aerway and a GA 24 on greens and tees.
If you have the budget for it, I would get both the shatter tine and the sports tine for your fairways. It would also depend on the condition of your fairways and what you're trying to achieve with this. I use the shatter tine once / year. The sports tine is great for going over dry spots in the fairway and rough. Very fast and effective and not at all disruptive to play.
Cheers.
