Me also - less is best, as far as the pan charge is concerned.
FWIW, I have a .50 rocklock that I've been getting virtually instant ignition from, for the past 7 years, since I switched to FFFg of Holy Black for both the main charge & the prime.
The fast ignition renders much better accuracy, since the barrel has less time to "wander".
The only time I switch to a caplock is during VERY inclement weather, like actively rainy/snowy days.
