I have had both and I have the sparks right now. I liked the HMF alot but I wanted to try out the sparks so I sold the HMF for the same price I bought the Sparks. I feel the sparks pulls harder off the lower rpms.

the sparks pulled harder than my rossier in the first few gears for sure.....i never tried all out in the upper gears.
