I thought you said isometrics were useless.

If you perform deadlifts, train back without straps, and do standard bicep training, I don't think any extra forearm work is warranted or necessary. I think you answered your own question when you mentioned that you did deads first, your forearms were already exhausted when you trained you biceps. I think the extra forearm work being recommended here will only cause you to overtrain them (considering all of the other things you do).
