TaeKwonDo kicks my behind

Hello fellow Martial Artists!  My MA of choice is TKD, but unfortunately when we moved from South Texas to Washington State, I lost the school I'd been with for all of the 3 years I've been practicing.  I did look into other schools, but the closest one is about 150 miles away, so I had to go to a different one.  I discovered that different schools are TOTALLY and COMPLETELY different.  Including how you start, speak, answer up, spar and practice.  I'm pretty deeply wedded to my original school, so I'm being a weenie about joining what is pretty much a completely different Martial Art.
