Giving a touch more realism than your standard dumbbell eyes, Spirit River I-Balz are a great way to add eyes and weight to your flies. Crafted from brass and available in a few different sizes and colors, these eyes are super durable and have enough options to really dial in your presentation and depth. Great for use in saltwater and freshwater patterns, I-Balz ensure that your flies are always getting down right where you need them.

Uses

Spirit River's I-Balz are designed for adding weight as well as realistic eyes to your patterns. With a clear pupil, these eyes do a great job at imitating naturals, and with their various weights, you can be sure to get the right choice no matter what size fly you're tying. Also, I-Balz are an excellent way to create that jigging motion that's effective for a ton of different fish species.

Comparisons

While there are a ton of different dumbbell eyes on the market, only the I-Balz offer a realistic and circular look. However, if realism isn't what you're after and you still want an eye crafted from brass, then Hareline's Brass Dumbbell Eyes would be a fine substitute.
