This is not strictly true. Blade life is inversely proportional to
the most acute angle that it must turn through. Since there are 3
wheels, the blade does not need to make a 180 degree turn on a single
wheel, and so the wheels can be smaller, and still (if properly
designed) have LESS blade bend. This is not to say that all 3 wheel
band saws are properly designed.
I have never seen Inca's 3 wheel model, but have you ever looked at the DO-ALL
3 wheel model. (Please note that Do-All only uses 3 wheels on thier big
36" saw.)
