The Deer Creek 6/7 wasn't one of the original line up which is why there is no info on the TFO
website. I'm not sure why TFO
hasn't bothered to upgrade their website.
I found some good info with a quick Spey Pages search. You have already seen it, but maybe not.
Here's an opinion on lines for this rod you may not have seen. Tfo dc 6/7 13'
Here's some info on this rod right from the man himself, Mr. Meiser, one of the Deer Creek series designers.
The grain window for the Deer Creek 13'0" 6/7 is 400 to 600+ grains.
Skagit shooting heads: 450-500 grains <> Tips to 150 +-
Scandi shooting heads: 400-450 grains
Classic Speys to 550 +- grains
Speed of recovery: Fast/Medium fast
Flex: Uniform progressive
Suitable for all game fish from 5 to 15 pounds+
She is very similar in flex and speed of recovery to the Deer Creek 13'0" 7/8 but down grained by net 100.
The rod is a delight to cast <> A hard working, caster friendly, durable mid power rod.
