What are your goals?

I can say if you want to see anything but stunted LMB, I'd stock regular BG and not HBG. If you don't care about bass growth but want to focus on HBG growth then that combo is OK.

Many think it's overly challenging to grow quality BG up north so they resort to hybrids. I say baloney! You just need to stock the right species at the right sizes at the right times.
