Do you know what kind of brass alloy they use? This was discussed in a Torque v Trinidad A thread and Shimano cited frame strength and gear alignment to dismiss concerns that their gears are soft. They didn't say that the alloy they use is as strong as or stronger than SS.
Lots of guys did extremely well this year with the Talica 20 at Guadalupe. They freespool extremely well and catch a lot of fish. I'll be fishing other reels if I can get off the waiting list
Does it matter if the main gear is brass, bronze or stainless steel? All that matters is it works well. The pinion gear has the wear issue, times the reel ratio.
