Rye ratios

What is the highest ratio of rye you have successfully used in a beer? Any issues other than stuck runoff? I tried searching for a thread on this but I only have the phone app right now (shhh, Im at work). I'm looking to do a beer that is mostly rye and was wondering how far people have pushed it. The more details the better (recipe, style, equipment, yeast, tasting notes...). Thanks!

My standard RyePA is 25%, and I've never had a problem with sticky mashes, no protein rest, no rice hulls, crushed at the same mill gap as the rest. I know people here have gone higher, but I like the slight hint of spiciness with the Amarillo/Simcoe dry hop combo. You can definitely tell it's there. Here's my recipe:

8lbs Pilsner
3lbs Rye Malt
0.5lbs Carapils
.25lb Special B (not necessary)
Mash at 155F
0.66oz Chinook (first wort)
0.33oz Chinook (10mins)
1oz Simcoe (0 min)
0.5oz Amarillo (0 min)
1oz Amarillo (dry hop)
1oz Simcoe (dry hop)
PacMan Yeast
