i think weve got to stop confusing the poor guy more.
keep it simple.
dude..its just that the conventional way of pickin is with ur index finger and ur thumb..but there have been many players who have had a diff pick grip.
try the conventional way..first..then if u think u can be more comfortable using ur other fingers do it..and in the end u urself will know which is the most comfortable for u.
dont listen to too many ppl..
