Grease may be applied, but in judicious amounts. There are plenty of open vista type twisties, etc that are not blind, but a lot that are as well. You've been on two wheels long enough to know the difference, just mentioning it is all. TexCav (RIP) went down on the sisters when we were all down there a couple years ago, but he wasn't anywhere close to your experience or skill so not really a fair comparison. The single biggest concern I have when riding that area is critters. Everything from giraffe's to feral hogs...and that isn't a stretch. Lots of exotic game ranches in the area and it's not unusual to come around a blind corner and have a zebra staring over the fence at you...sorta distracting. I also don't ride after sunset or even close to it if I have a choice. Deer are thick as flees on a dog's @ss. Last time we stayed in Leaky and when we woke every morning I would go outside and drink coffee while watching 150+ head of deer have their breakfast drifting through the pecan orchard about 20' off the back porch. This is definitely one of the "Must Do" rides in Texas so I wouldn't want to scare you off, but caution is advised on your first run through.
