just look at the difference:

the strechlet1 (solid)
orange: RepG026 original Ultimaker marlin2
silver: Netfabb, standard hollow (only outer, the rest disabled, every half layer, fine, snake, seam near origin, contour count 2)
because only the outer is active with snake it starts slow, and it attaches better to the tape.
