I had Carter guides on my old Delta bandsaw and while it took a little while to get used to them, the eventually became very easy to adjust. I sold that and bought the same Laguna you have and have found the adjustments somewhat easier since the guides actually touch the blade, albiet very lightly.
I generally keep a half inch blade installed so I haven't had much need to adjust the bottom guides. I think based on my Carter experience, that you'll like them. Follow their instructions on installation and you should have few problems. Don't let the back guide ride on the back edge of the blade, It should be close, but only touch if you press on the blade. How the blade rides on the tire is also important, I like the back of the gullet to ride about center on the tire.
You'll want to be careful not to let their 3/4 Resaw King plade's tips touch the Carter guide, It will likely damage the blade and/or the guides. I have a little 12 inch Rikon/WEN saw with a narrow blade mounted for quick and easy cuts in my shop, which is easier than changing blades in the Laguna.
The more I do, the less I accomplish.
