For GTF and I am really NOT trying to disparage here, I feel that I have done several improvements to the way this style of case works and protects cues and to the overall durability. While the appearance is similar the guts and construction of our cases are substantially different. The others are good, well made cases and I just think we have managed to find a few spots where we could tweak the construction to make an even better case.
It's true. The GTF is better IMHO.
There is in fact only one thing wrong with a GTF case....it's not a Fellini!

Maybe in 20 years they will gain that legendary status...in the mean time, they are simply superior cases.
