It sounds like you’re looking for information on the T4 Cortland Fly Line (444 Floating) and possibly its suitability for deep nymphing, along with a mention of “3 boxes” (which might refer to fly boxes or other gear). Here’s a breakdown of what you might need:

1. Cortland 444 T4 Fly Line (Floating)
– Model: Cortland’s “444 Classic” is a well-known series, and the T4 likely refers to a weight-forward (WF) floating line with a 4-weight (WF4F) designation.
– Features:
– Floating: Designed to stay on the water’s surface, ideal for dry flies, indicators, or shallow nymphing.
– Taper: Weight-forward for easier casting at moderate distances.
– Durability: Cortland lines are known for their longevity and smooth coating.

2. Deep Nymphing with a Floating Line?
– A floating line (WF4F) can be used for nymphing, but it’s not ideal for deep nymphing (where you need to get flies down fast).
– Better Options for Deep Nymphing:
– Sinking Tip Line: A floating line with a sinking tip (e.g., Cortland 444 Sink Tip).
– Full Sinking Line: For deep water, a Type III or Type VI sinking line is better.
– Euro Nymphing Line: A specialized thin-diameter line (like Cortland OmniVerse or Competition Nymph).

3. “3 Boxes” – Possible Interpretations
– Fly Boxes: If you’re carrying nymphs, you might have 3 boxes for different fly types (e.g., heavy nymphs, emergers, droppers).
– Line Boxes: Could refer to spare spools with different line types (floating, sink-tip, full sink).
– Other Gear: Maybe a reference to a 3-box fly fishing system (dry flies, nymphs, streamers).

Recommendations
– If you’re nymphing deep, consider a sinking line or weighted leader.
– If you’re sticking with the 444 T4 Floating, use split shot or a heavy nymph to get depth.
– For Euro nymphing, a thinner, more specialized line may help.
