I've had the same debate. I struggle to get a krab into the side slot that's strong enough for a chainsaw. Right now, I keep a kong on the right ring and clip it into that. I have to turn and look to clip the chainsaw into it every time, but other than that it's working pretty good.
I've been debating on cutting the ring out though and replacing it with an accessory krab. That way it doesn't flip around and always stays one way. Only thing is it would have to be smaller than the kong.
