Fish tailing arrows

[flinginarrows]

Just started shooting 3 fingers under with a tab. I know I am torquing the string but I dont know how to fix problem. My accuracy is good but some shots have alot of bow noise and fishtailing. While paper tuning some shots are bullet holes but others have a bad right tear. I believe my spine is ok but I am suffering from shooting errors.Thanks in advance for any advice.

I'd bet it is limb tiller. Many bows do this when shot 3 under.
