I've been thinking about getting one of the Richardson chest packs, but don't know how much room I will need (ie how many trays I might need) Can anyone that owns one offer any advice. When using a vest, I generally carry about 3 medium fly boxes, a few spools of tippit, tin, and floatant. I probably carry an average amount. Also, I would be curious to hear about any options that people think are particularly useful or useless.

Thanks.
