That's what I have for this winter. Some say it's not enough others say all you need. I am tired of all headaches with traditional studs. Pavement and rocks are super hard on traditional studs because of deflection it causes. I know some trails in central region of Ontario I wouldn't go on without proper studs.
given you have this experience, go with what you outlined originally - you know what you're getting, what you're doing, and what to expect.
It's a good set-up and you will enjoy the hook-up.
Like I said, its personal preference, but seems clear you prefer having them and enjoy the traction they give, so go with what you outlined, it will work awesome.
