the Featherweight is the better choice as all have said , just make sure as said before ..put plenty of backing on it , makes the fly line into bigger coils when on reel .
I use a Ir2 for my 1wt balances my 1wt orvis trout bum rod perfect, thats a 4wt Reel , I got a spare spool from Islander ...cut some grey pipe lagging to size ... clipped it onto spool to save too much backing....then 50 yards of backing.. then the 1wt line (WF1).
the other spool has a wulff tt wf4 plus 100 yards of backing . I carry as I said before 1wt and a 4wt Rods both 7'6" in a custom leather & canvas Tube I made . fits perfect in my DXL backpack , covers all my stream fishing
your choice of the featherweight will be fine... if you don't like the reel I will have it
