I was wondering if a gsm and an black and white could or would ever possiblely pair up. as of the moment my black and white is about 1 1/2 to 2 times the size of the gsm. they don't seem to get along the black and white sometimes chases at the black and white if the gsm gets to close to "his" rose BTA. I have two BTA and an sea bay. THe black and white has the larger one and the gsm gets the other one.
