Yes, I still use MELFs. Regular and mini MELF.

They are round and they can roll but place a Coke Bottle on wet sand, 
give it a slight push down and it does not roll.

I think the biggest problem with MELFs is spinning them to the correct 
rotation when using a flat steel Pick and Place tip. If you use a tip 
with the rounded end then no problem.

And I have always used rectangular pads with no problem. I like MELFs as 
they solder well and tend to be very easy to inspect.
