You will not find a sleeker case on the market than the GTF Replica. That case is about as efficient and seamless as a case can get.
The J.Flowers tribute is bigger and heavier and has much more room inside.
Both of them represent almost opposing ends of the case design spectrum. Jay of course, brought us the western saddle look. Fellini popularized the sexy little black dress look.
Both the J.Flowers Tribute and the GTF Cases have the padded snug fit that I brought to case making. So either way you do get much better protection than with the Whitten. As you know with me it's not about the beauty contest because honestly Whitten is a front runner all the time in any such contest involving which case is the prettiest.
So you can't really go wrong either way for the two choices you have narrowed your selection down to. For me personally I prefer the elegant sleek look of the GTF over the western tooled saddle look of the J.Flowers.
For the rest of you here is why protection matters,

You don't HAVE to have the level of protection I offer but if something happens where the level of protection my cases offer would have saved your cue then you'll be glad you have it. One of my slogans when I owned Instroke was "Look Deep". And often when I pulled the guts out of a competitor's case and showed them to the customer, mostly Instroke knock-offs, the customer would be shocked and disgusted to see what they had been putting their cues into.
Someday I will simply put up some pictures of ALL my competitor's interiors and let you all vote on them without identifying the brands. I think that this will be a revealing exercise as most of you have ZERO clue what is below the first five inches of the inside of your case.
As I said to some of the cue makers at the recent ICCS, "if I handed you the material used in the some of those cases and asked you to polish your cue with it you'd ask me if I am crazy."
Said as I was handing out this to people as a demonstration of what's in our cases,
