Evaluating Managed Funds

[z32fanatic]

What's the difference between the 5 New Insight funds he manages? I see 2 of them (New insight A and T) have loads while the other 3 (New insights instl, C and B) don't have loads. They all have similar performance and holdings. Why would i buy one with a load if the other ones are no-load? If these questions are dumb please bear with me, i'm new to the mutual fund game. The symbols for these are FINSX, FNIAX, FNITX, FNICX, FNIBX.
