Hi, Eric
I don't have personal experience with those F-products, but the price seems to be "a bit" steep

.
I'm using an old beat up Warwick RockStand for 5 instruments, and I think it's great. I did change those plastic angle thingamajingies for stainless ones, but otherwise a solid product.
They're around 60€ I think?
BTW, the ONLY stand to hold Thunderbird without modifications, that I've found.
Just my 0,02€
