X2, bought the Fastback top way back when Viking Offroad was making them and recently just purchased a replacement from Rampage.
It's a great top that stores the sides and windows up out of the way and you can zip them back on in a pinch if an afternoon storm rolls in.
Although Viking discontinued making them fyi I think it was a bit thicker and more durable top, the Rampage Fastback in my opinion seems to be more cheaply made/thinner material...we will see
been pricing/researching them also for my wrangler.The Rampage is roughly half the cost of the Bestop yet the Bestop is a sturdier unit.Looks like you get what you pay for.
