Joe, I have an IC-718 and experience with eleven other transceivers.  I
have found the 1.8 filter for help in SSB of only some help;  often the
offset control will do very well.
A 500 filter for CW is a big help, but a real help only to CW operators who
can not tune mentally.  Some CW ops can tune mentally and like a wider
passband and do the filtering in his head.
So, if you have such a CW op, keep the 1.8 filter.  Otherwise, get the 500
and let the SSB ops cope.
Good luck, Charly
