Total Noob Question : T-Taps

with t-taps there is a high chance for them to fail and then you just waste time tracking down a fault in the system.  Do it right the first time and save yourself the headache down the road. 

100's and 100's of installs using T taps and I can't  count the failures on one hand.

ANY type of crimp connector requires the proper way to make a good tight connection. It's SOOO simple to do it wrong, most just think connectors are inferior. Connector color in relation to wire size, orientation of..or even brand of crimp tool all come into play. Almost ALL installers that have problems crimping, have been found out to be holding the crimp tool upside-down! 99.9% of all crimp failures are the result of not enough pressure on the crimp.

Then again, I believe I read somewhere once that many many installers cannot solder correctly either.

This topic is discussed over and over at the tech schools and the result is always the same. In front of the class they'll tell you to solder, one on one they'll admit there's nothing wrong with crimping if done correctly.

Of course there are times when soldering is neccessary, AND important for a good connection and current transfer.  Just way too time consuming for every connection.
