I never had reels on my rig. Having used reels on other's rigs, the only reels I liked were those with carefully designed electric winders.
Most reel systems downfall I see are in my opinion, the reels are too small of diameter.
In this day and age of "methed up" copper thieves, I would probably build my next set up with wells again for security reasons only.
Thieves are by nature predators of opportunity (out of sight, out of mind!). So unless they have reconned you or have specialized in welding lead heists, you are safer with wells and your $1000.00 copper investment tucked away from sight of the zombie tweakers.
The wells do make for a neat and orderly looking bed, but are a pain if you have a short bed, tons of gear, muddy leads and in wintertime can be as stiff as a honeymoon johnson first thing in the morning... don't lay too flat on uneven terrain/tripping hazard.
For overall speed and ease (manually operated) of lead storage, a large looped pair of hangers gets my vote.
