Black Max 1600 Information?

Asked on another forum since I know there is an Abu guru there, but got no replies. I picked up a few of these reels, but know nothing about them. I did find a site with a schematic drawing of the reel. Seller may have mentioned the gear ratio, but not sure and not where I can check his correspondence. One poster mentioned in the ad that they make great cranking and spinnerbait reels. First reel is going on my 7' cranking rod so I can switch the Fuego to one of my new Fenwick Smallmouth rods.

Interested in any information you may have including any links to reviews.

You may wonder why I picked up a reel I know nothing about. Well, I've been wanting to try a round reel. Specifically one of the smaller Abu reels. I have since found out that the Pro Max is a hot rodded Black Max, but had a paint job instead of being anodized which makes the finish nowhere near as durable as the one on the Black Max.

Seller said I would be surprised at how well it cast. I don't like tinkering as a normal rule. However, this is one time that I would try any upgrades myself given the price of the reels, and that Abu reels are suppose to be easy to work on. Sorry Mike! You know you've been getting my other reels for cleaning/upgrades.

Also can anyone give me information on the 4600 UC reels? I've considered purchasing one of these as well, but have no knowledge of this model either. I only got back into fishing 3 years ago, so there are tons of reels I know absolutely nothing about. Thanks.
