Punch down tool

[wkearney99]

Yep, repeat punches will force the terminals to spread.  With 66 blocks you can use pliers to squeeze 'em back together.  110 is less forgiving.  With either style you really want to only use the connection one time.  Pulling the wire and punching it down again, especially if it's the exact same spot on the wire, leaves chance of the connector being just a bit too wide and not getting a solid connection.  It's just one of those little things to avoid doing.
 
The twists are important but I wouldn't get fanatical about it.  This is where the snipping action of the punch tool is useful.  Un-twist enough to get all four pairs seated and let the tool remove the extra lengths.

Should always have tool set to high.
 
Low is for something like using the screw starter tip.
 
Keep in mind, repunching the same terminals can cause issues.

The instructions from Fluke say:
"Automatic spring handle --choose low impact for 24/26 gauge wire or high impact for 22-gauge wire"
 
but I will go with your experience and try high impact.

After using them for a bit or with used blades, it's more common to swap over to high.
