I'm finding the + frames off this corner re-stand to not be nearly as positive (or consistent) as the mid screen b3 restand. The plus frames are based off of how high they are, hence why I deleted some of my previous thoughts on this.
That being said, I think I'm finding the b1 bf2 re stand a bit easier with this set up. I need to practice more (but +15 is cool if you can get it w/o whiffing). I walk directly under them, d2, then b1bf2 towards the corner at head level (no side switch, no stepping after d2) only time will tell if I can do this consistently tho :/
