I have a few older Revos and on two or them (STX) the drag is a bit peculiar. I have to wind it down quite a bit to get to a "sweet spot" where each click seems to do something useful for say lighter line and ripbaits, but then if I want to really button it up the clicks make minimal difference. Then one more click and it's in lockdown mode. I am punctual in backing off all drags fully after each days use. Are the drag washers just plain worn out? I would be surprised cuz I really don't use these reels much in the past few, and frankly, the size of the fish I'm catching these days don't warrant much drag consideration, oh well. 

I've had 6 Revo's Gen 1 and Gen 2. Each ones drag suffered quickly. I disagree with Abu's dry drag theory. My Gen 1 Premier's drag was useless right out of the box. Each Revo's Belleville washers, the ones that look like this, () wore out quickly and had to be replaced to increase drag range. Abu's tech agreed with me that the factories habit of shipping reels out with the drags somewhat tightened, meant the washers had been compressed for who knows how long. I don't think it's the best quality metal either. I'd also run the drag slightly wet with Cal's grease.
