I just bought two Made In England Orvis BBS IV reels for my 6wt rods. The
Made in England instructions indicate that this reel is for 6-8wt lines, but the
Made in China instructions say 7-9. I put backing on until the backing was
1 7/8" in diameter, and then added a 6wt WF F line. I was left with a bit less
1/4" of space between the line and reel, and the backing diameter has made this a mid-arbor set-up with a twist: the BBS IV weighs at least an ounce less than Orvis's mid-arbor reel, and that's before putting an ounce of backing
onto the mid-arbor. I can take backing off, and use a heavier line, or even
put a 5wt line on there to balance a 9' 5wt. I do like to go with the lightest
set-up for anything 8'6", 5wt and under.
I have some wider large arbor reels, and the only problem is weight and possibly jamming. Using a line at the upper end of the manufacturer's
recommendation increases the chance for jamming if you don't pay attention
to winding line back on the spool (my wife
). If I remember correctly, the
Lamson 1.5 reels are about 3" in diameter. I'd go a little bigger for the reasons
mentioned above. You could buy two Okuma SLV reels for the price of one
Konic, and the SLV is every bit as good as the Konic. I've owned several
SLV's and never had a single glitch of any sort.
