Thanks BobCo19-65 and Arthur P for offering your information. I'm trying to educate myself before spending the $90+.

I'm not trying to start a debate on punching versus smooth releasing. Perhaps punching isn't a good word for what I'm think of. I'm simply saying that there are times in the field when it is necessary to expedite the releasing process. This may be at the expense of a bit of accuracy but if the group grows from 2" to 3" at 20 yards, I don't think the drop in accuracy will lead to wounding. The 'expert' was saying that the drop in accuracy is more drastic with the t-grip. I seems that there is disagreement here, which is what I wanted to hear.

You bring up a good point Arthur P. I never thought about the "renocking" concept that you speak of. Avoiding the hard connections does make sense. I wouldn't agrue that the string loop is easier on the bowstring. The single/double ball seems like clap-trap to me. I just wanted to confirm that there isn't a distinct advantage of having one that outweighs the negatives of extra clap-trap. I'll either go with the talon or the standard caliper. It sounds like the talon is only meant to be used with a string loop, whether it's fixed to the release or the bowstring. I'm not sure which route I'd go, standard vs. talon.
