Try to work with pure b/w film and find out what is best for u and stick with 3-4 type. That if u r a die hard b/w user. My 3cent. 
It is alway good to know your filter. But, use it correctly. Red filter is not really good
to work on ppl. I am not a pro. Just sharing what I know here. My advice keep shooting,
read and see how the pro work. Soon u will be just like them..
