What obviously is going to work best for them is already being done with the vibram open. Being that I am no where near where it takes place and likely never going to have the resources or time to get out there, I am dependent on hearing about it through coverage and word of mouth. From what I have heard and seen is that it is one of the biggest and best tournaments around; something I wish I could participate in. Not bad for a "word of mouth" tournament.
The same strategy will have to work for sales too. Innova and discraft are too entrenched for outright marketing. Thankfully vibram is very successful with it's other lines of products, so disc golf does not need to make or break them. They have the time and resources to make better products that in turn can spread positive word of mouth. If they can produce a whole line of quality discs, they can almost follow in the wake of Lat64. The Jasper series of discs followed by the River, Fuse, and now the Flow have definitely put them on the DG radar. Retailers in the know should and likely have no reservations pushing Lat64 products despite having a healthy stock of innova and discraft. If vibram can come out with another quality disc soon, a complement for the Ascent, they should be in good shape. The Ion by MVP is a good disc but I bet that it is going to be getting far more attention and sales if the new Vector comes out and is as equally good.
So, honest word of mouth can go a long way. What really helped, at least in the short run, is when Steve came out to GGGT last summer and gave a putting demonstration. That personal touch got me enthusiastic and I can count at least five other people I know who bought vibram putters because of what I said. Now I know that us six cannot sustain a business, but there have been numerous times i have been out playing and people see that yellow logo on top of that disc, have no idea what it is, and ask what it is that i am throwing. That is the exposure they are going to need.
