Bigcountry,
When you bend like that and your bow is canted so far, do you have a different point of impact? It seems to me that the more I cant my bow, the farther right I hit.

I've been thinking about this, and I'm pretty sure that if I turn the Viper to where it's facing almost directly away from the trail but turned just a bit so that the right front corner is exposed, I should be able to put my left leg against the rail in that right front corner, stand straight, cant the bow normally and it should clear everything.
