So I was doing some testing, and about 2-3 weeks back, I found that flat wallbugs are consistent with the right timing, though the timing is dependent on the horizontal angle looking at the wall. This find can lead to skilled wallbug strats that are as consistent as bounces/bouncehops. I am losing interest in jumping, slowly, so I'm just throwing this out there. Do your own testing if you want, this is a very interesting find, you can see what results I have come up with in this text document

tl:dr: flat wallbugs are consistent with the right angle and timing.
