Since your interest is weak signal CW but not contesting and you don't 
have neighbors blowing away your radio, a roofing filter is not a 
particularly high priority for you. Instead, I would concentrate on the 
best RX antenna(s) you can rig, and buy the sub-RX when you can so that 
you can use it in diversity mode.

If you DO decide to buy a roofer for CW, I'd go with the 250 Hz filter, 
because you can cascade it with the IF filter when the going gets rough.
