I'd say yeah, it's a gimmick.

Spinning reels are by nature prone to line problems, messing with the spool geometry does not sound like a good idea in my opinion.

Secondly, there are already an infinite number of ways to alter the action on any given bait, either by different rigging options or altering the retrieve.

Gimmick, can't say. ...

But being the company is New Zealand & Australian based.

The reel has a moveable part in the most vulnerable of places on a spinning reel, when it fails your going to send it for warranty work or even service to New Zealand?

Wonder what that turn around would be.....

I would stick to US market reels.....

Tight Lines!!!  

I do know one thing they are Rapala reels and i have 3 of them i love um i dont no about that spool thing though like RM says more to go wrong and long ways to send um for service
