was wondering if anyone knows who makes a 10', 2pc, 8wt fly blank

Rainshadow Revelation has a two piece 10’ 8 weight (REVF1008-2SB).

It makes a nice steelhead/coho rod.

John,
CTS also makes an Affinity-X, 10'0", 2 piece #8

Not for nothing- but has anyone asking about 10' fly rods except for Euro Nymphing- ever casted a 10' fly rod???
They are not pleasant to cast unless one is exceedingly strong and fit.

I've casted many, the Rainshadow blank above when it was called the RX7, overhead casts beautifully within the reasonably expected ranges with a timing that novice and intermediate casters can use quickly, roll casts, steeple casts and side casts nicely under, or over trees and brush. Throws and roll casts up to 300 gr. 24 ft. Teeny Tip sink tips well. I'm no body builder and have fished this blank multiple long days. My 9ft. 9 in. GL3 G Loomis 8 wt. rod has been far more destructive to my shoulder than this blank over time.

Past yrs I've used a 9ft 2pc orvis fly rod for Browns and steelies. The past several yrs all I use are 10ft rods and I'll spend 8 to 10 hours a day throwing flies, I've estimated 1,000 casts a day, i've got no problem here doing it. Between now and the winter's freeze I'll total around 3 weeks doing it also. Just never cared for the 3 or 4pc blanks.
