My company does sports fields and indoor gym turf installations for schools and fitness centers. We have been using GST's trainers turf for the past 3 years and it has amazing. The quality is extremely durable and we have not had many complaints from out customers. Many of the gym projects we've done are still holding up nicely even after years of traffic. In terms of quality and durability, I think GST is the best bang for your buck. I would recommend getting some samples to make sure!
