TwoHands,
True. I even do that, but it is a prejudice we should try to wean ourselves off.
However, on the other hand, look at the recent number of "pearlized" and hybrid balls, some manufacturers have released that they are marketing DULL as oilers. I have avoided them since many I have to eventually polish to be able to use on the amount of oil I see. Balls drilled for a semi-strong reaction, when polished, will tend, for me, to become too flippy to control when they are based on pearlized balls, and, to a lesser extent, Hybrid balls.
So if I want to get a stronger ball, for my own sake, I tend to stick with solids. I see more pearls with strong backends than solids, although they are making more solids with very strong backends. Some examples start with the Virtual Gravity and end with the newest Mass Eruption (according to the current issue of BTM, a very strong backend).
Still, as someone wrote a long time ago,
"You buy a ball reaction, not a (specific) ball?"
