Flash, how the heck did you break coat hanger wire in half while pulling on it lengthwise? You must've been cranking down pretty hard on it!
I agree with everyone here. Go to a wire pull fid. If you MUST stick with the push fid, you'll have better luck stepping down to the smallest size fid that will accomodate the tail you're working with. Taper the last 4" of the tail so that it will fit into the smaller fids. Tightly tape the end of the tail to form a bullet and insert that into the end of the fid, then push the fid down the rope by pushing the end of the pusher INTO the bullet you've made.
What kind of rope are you splicing?
For the record, I think that when properly used, push fids ARE faster than wire fids, but that they also take practice and don't work well for 16 strand rope, Blaze, Velocity, and Tachyon... which makes most tree guys say "stay away from push fids!"
So, yeah, Fairfield- get yourself some wire!
