[Elecraft] K3 Filters (again???!!)

[PETER HUTCHISON]

I appreciate that this is somewhat of a thorny / subjective issue but a search of the archives actually revealed very little in the way of useful information.
 
I'm in the throes of putting together an order for a K3 kit after being given the appropriate financial go-ahead. However, the issue of suitable filters is still to be finialised hence this plea for help. 
 
What filters would be suitable for a station that is primarily interested in WJST modes namely FSK441 and JT65B on 2m? Also, some 2m contest working from the hills where just occasionally there are some big, wide signals to contend with. Very little, if any HF use is anticipated.
 
As I said earlier, this is a subjective issue but all opinions will be of use as although I have the go-ahead the price of the filters in the UK being what they are I don't want to make a (costly) mistake!!
