NCKS | I'm still learning about this too. But from my research and what I have gleaned from others, at that pH you will want to go elemental sulfur first. In theory the Ca and K ions are the biggest so they will resist leaching the most while the Mg and Na should leach more readily. You need to send your sample to a lab that actually tells you how much Sulfur you have in your soil. You've maxed out what they will report. You may be able to call and get the actual amount of sulfur you have in your soil. Someone smarter than me will come along and say why that matters. I just know you already have a boatload of sulfur already in your soil.
Here's a question I posted last month, but I'm not sure it helps in your situation.
