Should get the HPI A886, it's what I have and has two sets of the spring/tension clips.
Gold = high stall rate
Black = standard stall rate

The HPI A885 is a good set too (but still has a wrap around spring) adjustable stall rate by cutting the clutch shoes.
you dont adjust the stall rate by cutting the shoes, it comes with 3 holes to put the clutches in and depending what hole you put it in gives you the different stall rate.
