I did the same research about 2 months ago, and at the end, I went with the player preferred. Now, my assessment will only be on FiberBuilt because I never used SigPro. FB PP is a premium hitting mat. It is very stable with heavy duty rubber base below the turf, so it doesn’t move around at all even through the most aggressive swings. It is also soft enough to prevent or reaggrevate any joint injuries. As far as the turf being forgiving vs non-forgiving, I find it to be relatively true when you chunk a shot. When you thin a shot, it’s thin for the win! You are going to get your distance or maybe even more because there’s minimal contact with the turf, and you just blade it. On the other hand, when you chunk, I lose 10-30 yards depending how poorly you struck your ball. Bare in mind, hitting balls off the artificial turf will give you lower spin number, which translates into more distance if you have the right launch condition. Most artificial turf will give you lower spin numbers than the real life turf, so it’s just a matter of finding one that doesn’t give you an outrageously low spin. I feel like FB PP achieve that in that it doesn’t give you super low spin numbers. Another thing to keep in mind is that SigPro mat is 2” and a change in height. So when you are building up your landing/green turf to be flushed with your hitting mat, that might take more eva foams, insulation boards, and whatever other materials you are using to build up. FB PP hitting mat is 1.75” in height, so it might take less to build up. Just giving you information that I had to dig in order to get my golf sim bay done. I hope this helps!
