I spent some time talking with Sam before purchasing my enclosure and hitting mat. He gave me honest, practical advice, and never tried to sell me on any particular product. I ended up taking his advice on the Launch Monitor and on the 3.5w enclosure, rather than 4m wide (even though I originally was interested in the 4m wide), and I am very glad I did. The 3.5m offers ample hitting space and an immersive experience. I'm taking my time with the rest of the build, but am already really enjoying hitting balls 20m from my living room! I can't tell you how impressed I am with Bayside or their product!
