Let me just first say that for whatever reason, Dunlop racquets have rarely piqued my interest, so take my thoughts with the knowledge that I have generally had little interest in any Dunlop.
I agree with much of your post. The 16x19 thing is fine with me. It is the pattern I prefer and I generally don't like anything denser. I, like you, am not a huge fan of the cosmetics.
Now, with all that said, let me get to the real point. When I first heard of this idea and these frames, I was highly intrigued. A frame that you could potentially easily take apart and tinker with, making it longer, softer/stiffer, and whatever else, seemed really cool to me. I assumed you'd get what you needed when purchased and then you could sorta customize your own frame. Then, I find out that you can't. A 'Dunlop Certifieed' dealer is the only one allowed to do it. So, in the end its a cool concept that fails to realize its potential, IMO. Where I'm from, it would be a severe aggravation to take it to a dealer to change, but in truth, I wouldn't really want to fool with that if I had one next door. So, for me, I love the idea, but until it is packaged in a way that allows me to change the racquet myself, its just another racquet. And worse, its a Dunlop, which doesn't catch my interest much.
I pictured something like the Donnay customization kit...something that came with the frame or could be purchased to allow the user to make the changes themselves. I thought Donnay's kit idea was a pretty good one, FWIW. Annything that makes some tinkering and customization easier, more accessible and easily undone is a winner for me. And, I think this is a good idea as well, but not of much use until I can do it myself.
I also like HEAD'S new concept of different grommets to allow you to change the string pattern in a racquet.
What we need is a combo of all of them...the iDapt that would enable you to change length and alter feel, the grommets that would allow you to change string patterns, and the kit that would make it really easy to add and remove weight, especially in the butt cap. Then you'd have virtually infinite possibilities.
