Just thought id throw this out there as I saw rampage was last on this forum 4 days ago.
Bestop now offers there tops in sailcloth. Said to be 50% quieter on the road. Might be something to look into. Im pretty sure the sales of rampage tops comes close if not exceeds the number of sales for bestop as far as bronco tops go. That being said its important for your company to expand and keep up with the competition. Some of us bronco brothers build our broncos with the future in mind, not the past. Its great you started making tops in the diamond material but that will soon be as old school as "diamond plate" rocker panel guards, and multiple shocks per wheel.
If we look at the winches and there use of rope we will see that while some keep with the old school stuff (steal cable), more and more tend to favor new materials and designs. Remember that the use of spectra, dyneema, amsteel, and other HMPE ropes, were used and abused in marine application and widely used on sailboats for many years before they were adopted by the offroad community. And now the sail cloth being adopted by offroaders is just cool to me. Marine people always have the best of the best, and anything we can borrow from them is gona make our broncos just that much better.
The fact that bestop makes the factory Heep top and probably started making Heep tops out of sailcloth after the need for something "bigger and better" arose, makes me believe there onto something here. Maybe its a cheeper cloth? But maybe its that much better?
Just something to look into to possibly keep your company moving forward....and lord knows 75% of bronco owners want and can afford to buy newer and better products.
