You are mostly correct? Thinner wire is not as durable and bending it straight after catching fish is what breaks it. I have never had one break on a fish they always break when I try to bend them back into shape. Most of the time I use .032 for maximum vibration but I do use the .035 on 1oz baits. That little blue bender is nice when you do want to make a custom frame. I used it to make a larger frame for a 6 bladed bait.
