Ok things I like about the Pro Max...
-A little bigger profile is more comfortable in my hands than the Revo S's
-Bigger reel that holds more line but is almost an ounce lighter. And that .8 difference on the Carrot Stix is very noticable.
-Reels much smoother than my S's. Maybe I got defected Revo's, idk, but the Pro Max definatley reels smoother imo.
Things I don't like....
-The color
- Way to good to be true lol. Therefore, it wouldn't surprise me if I blew it up only a few trips in.
Besides that, 8 stainless bearings for the Revo to 7 for the Pro Max, Revo S is 6.4:1 the ProMax is 6.2:1, both have the Duragear Brass Gears. IDK if it is just personal preference but I know there are others out there that think it is a great reel as well.
The Black Max, wont put it in the category of these two reels, but non the less good for the money. Nothing too special though.
