I have the LX as well. Prashun gives ya the correct sizes and tooth counts. Those are what I use.
I have a local company that cuts my blades for me to 92 1/2". Don't have a riser, and I understand that the kit is not yet available for the LX.
I set the guide bearings just off the blade and behind the gullets as was stated. The thrust bearing is set just behind the blade-not touching.
I am very well pleased with the saw.
