This is interesting news. I have seen the .12 in action (and own one) and it is plenty fast. Not necessarily JP fast, but plenty fast. I've seen .21s that are fast in club races, but don't seem to be able to make it when the competition ramps up to the national level and above. With so many drivers leaving the engine behind, it makes me worry a little bit. Are there any big name drivers that still run the .12 at this point?
