Quite a bit of confusion here, but your figures are probably up to date. Admittedly my information is a bit old, but it came directly from Wulff a couple of years ago. Most of the information is for the older "double" designations. My info from them for the 7/8 is 29.24 grams (450 grains) @ 65'; no info from Wulff on 8/9 or 9/10; 10/11 is 50.9 grams (785 grains) @ 70', 61.2 grams (944 grains) at 80'; no info on 11/12; 12/13 is 60.89 grams (940 grains) at 70', no information at 80'. I also have information from Wulff for the single designated 10 as being 44.5 to 48.5 grams @ 70'. That's halfway between your figures for the 10 and 11 lines.
As I previously posted, I measured my own 8/9 and it measured 37.25 grams (575 grains) @ 70'. It's interesting that those figures would make it a 9 by your figures. What's confusing is that when Wulff changed all their "double" line designations (8/9) to singles, the new number was the LOWER number of the two for the single-handed lines (the old 8/9s are now 8s) and it looks like the new number for the spey lines is the HIGHER of the two (the old 8/9s are now 9s)!
Can I assume you guys got your information directly from Wulff?
The TT line spec info as posted on my website was furnished by Wulff on 2/13/04 and is for the single digit lines. Here is the info cut and pasted right off the e-mail.
TT-7-F 27.00 +- 1.50
TT-8-F 32 .00+- 1.50
TT-9-F 36.6 0+- 1.50
TT-10-F 41.00 +- 1.50
TT-11-F 50.75 +- 2.00
TT-12-F 59.25 +- 2.00
The 7 and 8 wt. lines have 65 ft. heads
but are weighed at 70 ft.
Bill, I noted the difference between what each of us posted and I have no explanation since you weighed your line. I have found differences in line weights as posted by the manufacturers and in lines I've weighed from all the major spey line makers. This used to really bother me and it is one of the reason that a person should try out a given line/rod combo "on the water" before shelling out hard earned $$$ no matter what the rod/line specs are or how many other casters can make it go. Take care, MJC
