[ICOM] 751 / FL44a filter question

Hello, Gary:
I am bringing my pristine '751A back online.  It has the standard FL-44A 
filter; any thoughts on what filter to add to the rig in the open filter 
slot?  My passions are SSB and RTTY, and I find I really listen more than I 
transmit, probably as most hams do.  The rig has the factory IF Shift, and 
S/N is 04449.
Any advice you have would be greatly appreciated!
Thank you,
Tom, ABØJ
Minneapolis, MN
