Are you going to use the drawbar on your bridgeport? If you do, tool changes are a little on the slow side, but repeatability and accuracy is unbeatable.
If you plan on using a conventional drawbar, you can make it tight enough to hold the collet with less chance of pull down.
I use the TTS system on my PCNC1100 with the power drawbar and if used properly, it's a great system.
I say, GO FOR IT.
