The brass tubes sink quickly in water, which is perfect for targeting deeper waters. The soft junction tube makes assembly easy and the clear liner helps with visibility when tying the fly. I’ve used them for several fishing trips and they hold up well under regular use.

Good quality brass tubes that perform as expected. The dimensions match the description exactly. Assembly is straightforward and the tubes stay intact during casting. Slightly heavier than plastic alternatives, but the sinking action is reliable.

I appreciate the precision of the machined brass. The internal plastic liner keeps the tube stable during tying. The soft junction tube adds flexibility when connecting to the fly head. Works well with my favorite dry fly patterns.
