The generic 3D swimbaits are slow sinkers. If you throw them out and do a regular retrieve, they run about 2 to 5 feet deep. You can let them sink deeper but they sink slowly.

I talked to TW about the Calcutta 400 and here is the deal. The regular Calcutta 400 has been end of lifed and Shimano is not producing any more of them. That is why its not on the site now because what they had is all sold out.

The replacement is the aptly named Calcutta 400B series. The Calcutta 400B, much the like Cardiff Series A reels are hard to get right now and Shimano is apparently backordered for quite some time. So there you have it.
