Okay, I've demoed standers and riders, and I'm going to need to stick with my ExM Turf Tracer 48. Now I just want to make the sulky more comfortable. I presently have the Velke X2. I have used the Proslide (have 2 of em), the Proslide is VERY comfortable, but I need something I can ride all the time -- lots of concrete to traverse on my small properties. I want something more comfortable -- I'm thinking larger tires would smooth out the ride, as would having a castering type sulky (the X2 wiggles a lot). Is is possible to add larger tires to the Velke X2? Or should I replace it with another sulky? Folding the sulky up is EXTREMELY important -- I need to fit all my equipment on an 8' truck bed. Right now, the Toro Tru Track looks the best to me. I can't believe I'm looking at a Toro product, but it looks good.
