V'force or boyesen?

I currently have v force 4's but I was hoping to get some insight from other owners that have some input the two systems

I can only give accurate information on full drag ported 1/4 mile asphalt cub motors so take this for what it's worth.

My son and I did a ton of reed valve comparisons and nothing ET'd quicker than V-Force 2's. 

V-Force 4's came in a close second and had a better low/mid range pull and would be my choice for anything but an all out drag motor.

VF4 are hard to beat.
