I switched to a True Fire X-Caliper from Bare Bow, tab, apache style after 35 years. The transition has been simple and quite effective.

What works best for my anchor (presently use a peep) I bring the string to the center of my nose and I have a kisser knot tied on my string that comes to the right corner of my mouth. This effectively locks the web (thunb of my right hand around the rear of my lower jaw bone.

I jusr recently switched to the relax to fire method of firing with my True Fire and I am considering switching to a No Peep before hunting season.

I haven' t had any problem in the transition and my re-nocking and re-fletching bill is proof that I am driving tacks . . . consistently and that aint bad for an old dog (timer) learning new tricks.
