When I first started shooting I used middle finger to canine tooth and nose tip to feather.  I switched to 4 fletch parabolic and cant use use nose tip to feather anymore.  Ive tried Terry's thumb knuckle under ear jawbone but must have smaller hands it doesnt reach with finger at eye tooth.  
Starting to try finger to jaw bone and knuckle under ear it adds around a inch of draw length too.  It doesnt feel comfortable not sure if because its new or just not going to be cozy.  

Any other ideas?
Thanks,

A lot of double anchor depends on physical structure, but for me the middle finger tight in the corner of the mouth puts my second knuckle right up under my cheek bone. I lose a fuzz in draw length, but its solid and consistent.

May investigate nose tip anchor at junction where fletch meets shaft. Then retain middle finger to canine tooth anchor point.

Note: You may find yourself having to relocate the fletch approx. 1/8" forward in order to maintain alignment.

I shoot 4 fletch and I put my nose on the feather.

Are you using 4 inch parabolic?  Do you feel you are poking your nose and head forward to get?
