Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
I've been rigging my rods the night before (or morning of) a trip with a fly already on the tippet, then just 'break' the rod down in halves and slide the whole thing into the case. get to the river, pull both halves out and assemble the rod, pull the tippet then leader out through the tip-top until line itself is free and begin casting.
