Dive Time: Once you begin your retrieve, the Fat Papa Squarebill goes right to work but its running depth depends a lot on the length of your cast and the diameter of your fishing line. With 12lb test Tatsu, this bait ran maybe three feet deep. If I were to fish this bait longer term, and needed it to get deeper, I'd switch to 10 or even 8 pound test line.

The bait is larger around its head and mid-section hence the name.

The bait has a very traditional and tight wobble. The 70 moves a lot of water and has really good resistance during your retrieve. Think of it like a full back in football terms while the 55 is like a scat back - very wily and evasive. Speaking of which both baits are very good at deflecting off obstructions as well as stopping and floating up if needed, to work out of a snag.

It is available in both a 70mm and 55mm size.

I had good success running this bait over the top of submerged grass ticking the top of the grass every now and then. Even those loose blades of vegetation were enough to contribute to the Fat Papa Squarebill's erratic swimming behavior and trigger strikes. They'd always come after a "tick-tick" at the top of weeds and not when the bait got caught up and I had to rip it out. Probably because ripping a bait out of the weeds with fluorocarbon is not as effective as when done with braid.

Conclusion: Squarebill fishing is like taking your truck or SUV off road. Some anglers will throw these baits up into the nastiest cover you can imagine, engage that four wheel drive, and slowly crawl the bait out of that mess. I really like square bills out in open water over the top of grass but of course, will toss them up close to shore and bounce them off rocks, stumps, over branches too - just not down the heart of a laydown! Of the two sizes offered in this bait, the 70 is probably more mainstream, but I really appreciate the 55. It reminds me of a more robust Speedtrap crank that used to be so effective on the California Delta. Just a small, wily, get it in anywhere type of crank. If you're looking for a new squarebill to try and want something that reminds you of those old balsa baits from just a decade or two ago, Spro's Fat Papa Squarebill is worth a shot.
