FYI-
I took some measurements to compare effective opening surface area of a 55mm w/ no sampling tube vs a 70mm w/ sampling tube.
70mm w/ out sampling tube: area = 3848 mm2
70mm sampling tube (calculated it is a rectangle 8x70mm): area = 560 mm2
70mm w/ sampling tube: unobstructed area = 3288 mm2
55mm area= 2375 mm2
Should be just fine with the sampling tube since it essentially makes the opening equivalent to 65mm which is almost the same as the 65mm Explorer TB.
