Mike,
Can I recommend a 6el LFA for 6m? You'll like the low-noise RX, the natural 50ohm feedpoint impedance and the easy DIY build. I only have 5 elements but it works great for both Es openings and weak-signal Meteor Scatter work. Coupled with a good amp, the antenna has allowed me to work Europe and northern Africa during recent band openings. Based on my experience, you wouldn't be disappointed.
