Powerbronze:

Pros - cheap
Cons - looks cheaper
Pyramid:

Pros: still affordable if you shop around, better looking than the Powerbronze
Cons: not sure about underseat access with cowl in place
Sharkskinz:

Pros: looks awesome
Cons: discontinued as far as I can tell, have to remove entire tail to get under the seat
Corbin Smuggler:
(only pic I could find without the beetle bags)

Pros: everything but the price
Cons: costs twice as much as my truck did, heavy
Airtech Race Tail:
Pros: Airtech quality, not too expensive considering it's the whole tail fairing and I need one anyway because mine is broken
Cons: Airtech quality (no predrilled holes or cutouts), looks like the Powerbronze, stock 2-up seat is still hiding in there
If anyone has any experience or input on these, or there are any other products I've missed, please let me know. I'm tempted to cut off the rear of the stock seat and make my own Smuggler-style solo tail, but my tail fairing is missing half the right front mounting tab so I've have to buy an intact tail first just to make a mold for a starting point.
