[Elecraft] K3 Filter Choices

[pastormg2 at verizon.net]

Hi Guys, in my quest to purchase a new K3 I am worndering about 8 pole filter choices.  I see that there is a 1.8 KHZ 8 pole ssb filter and a 250 HZ 8 pole cw filter that is avaiable.  If one purchases one of these filters wouldn't that basically solve the problem of not needing all the other filters at different KHZ?  This probably is a stupid question, but would really like to learn.  Mark KB3Z
