Idiots delight. File claim. Do not, I repeat, do not submit any post -service medical records to prove chronicity even if asked twice by the VARO. Do not help VA develop your case. Admit that both your brothers were in the military and they, too, have HCV. Proudly declare you were a firefighter with no medical risks for contraction of the disease. Pretend to be Dr. Kildare and blame the jetguns. Drink lots of adult beverages and make sure VA knows about it. Change your story a few time to keep them off balance.
P.S. Make sure your nexus /IMO is vague, plagiarized from the VA examiner or otherwise hopelessly compromised by no conjecture or reasoned thought for its rationale.

The Seattle regional office can smooch my rear stabilizer flaps too. Had to move across the country to get justice.
Talk about shooting yourself in the foot!
I just fired my VARO, felt good, 13 years of nothing, Hell You and me won the case, Now the BIG WAIT for 20% to 100% If I ever live to see it, but like you said Blood Work Dont LIE.
I must say that My Old VSRO really SUCKED, he was the KING of covering for the VA, I wonder how much THEY paid him to Slow everything down till I went away and gave up ???
To Bad my other brother Darryl gave up.
Good luck
