Jamie always does an excellent job addressing concerns folks are having with their guns.
I'd love to add, and maybe have Jamie confirm, that you should also be conscious of how you are lubing your Vanquish. Warm weather favors thinner lubricant and colder weather favors a thicker lubricant. Personally, I use Vitamin G on 50+ degree days and sl33k on <50 degree days. In a pinch, you can mix a couple of drops of gun oil in with your dow 33 to make a thinner lubricant great for those warm weather days.
I run my Vanquishes without the spring and my ABS dwell is also typically around 20ms.
