I use the YORO- YORO. This also has a rounded lip, but it only dives to about 30cm. Think this is the one you want. Ther is also a high pitch version which runs a bit deeper- haven`t tried that one yet.
ive got them both,i think the yoro yoro one dives a little shallower than the hi pitch one but i may be wrong! if you want it to dive a little shallower raise
your rod tip slightly. cracking lure,wouldnt be without one although the bibs are prone to snapping am after killing quiet a few gaterides over the last year or so
