The St. blue head Paloma is very similar to a Bonito, extra long stroke. The Ltd. edition is a standard long stroke (16.28x16.8) same as the P5 and most others. The ltd. edition is a 7 port, I thought it looked very similar to a Fusion X7. The ltd. does not have the Team piston and the Std. does. Power wise I am not sure, both would make great power. I am thinking the blue head for a truggy and ltd. ed. for a buggy.
I did not get a limited edition in but can order it if you are interested.
