Wing Tip Shapes

After looking at many different Pattern and IMAC models and even full 
scale for that matter, I noticed that the wing planform
for most aerobatic aircraft ends in a blunt tip.  I may be wrong about 
this but the information which I've read regarding aerodynamics
would suggest that this kind of wing tip generates drag as opposed to a 
highly tapered or fusiform shape such at a spitfire.
My question is does this type of tip help at slower speed and therefore 
that's why it's being used or why the blunt ends on
all the aerobatic planes?
