All the suggestions are top notch for sure, however If protection and economics enter into the picture I can readily, and confidently choose Instroke. If you review their specs, they offer arguably the BEST protection for your cues for the money... hands down. They also last forever and hold their value excellently. They have thought of everthing in design... even temperature acclimatization of cues.
I bought my first case, an Instroke 3x5 Premier for about 8 or 9 years ago. While cost was an issue at the time, I paid about $150. It was not leather, but really was a great top grade vinyl case. Instroke uses full, dedicated felt lined pvc tubes in there cases. I still looked almost new when I sold it for $150 shipped on Ebay a day ago (it had a custom sheepskin shoulder pad, that may have entered into the value element?
Over the years, the only thing that needed replacement was a peg on the bottom, and customer service sent them to me Gratis.
I fell in love with a 3x5 tooled leather Saddle Instroke case (style close to the Instroke saddle D03) on e bay that I had to have.
The seller was not motivated at all to sell it and was quite attached. Over time I finally offered him an extra $20, and told him I would appreciate it every day.
Bought it for $250 and It had a lot of character and richness and since it was also about 5 yrs old it did not have the heavy clearcoat that Instroke and others put onto their cases now, resulting in a harder looking glossy leather that some do not prefer. So the used case I bought was Retail $460, wholesale $367.20. I feel comfortable buying it for $250, and confident that I will always be able to sell it for that or more.
I spoke to Instroke prior to my purchase, and I can confirm that Instroke makes the WIN cases as well. I was torn between the WIN and the used Instroke, but was advised by Instroke that their cases offer the full tube protection, and is superior to that of WIN cases. I could not find any specs on WIN, but plenty on Instroke so the decision was clear. I researched forums and online to find out which cases I would be able to get for under $275. Compared things.
Instroke was the game changing cases that led to the the higher end customs listed. JB was a previous Instroke Company Holder and it was my understanding that many of the designs were from him mind.
All of the Whitten, JB, Castillo cases are great and I respect them all, but there is only so much I think should be put into them.... and they should not me more expensive than all the cues your going to carry INHO.
I will likely keep the Instroke case I know have for the rest of my life. I need not look any further.
Just my 2 cents worth.
Given what you are considering at this time, you are definitely looking at the cream of the crop.
I would not look at any other additional "production" brands for they would be a step down IMHO.
