I chose the 17/17 Monolite several reasons.
First, if I'm going to pay $3000 for a set of wheels I'd prefer that the design of all 4 was the same. It always bugged me that the front 16" Monolite looked quite different, and a lot less elegant than the 17" rear. But if you're buying these wheels just for weight/strength, then I'm sure this won't bother you.
Second, I've always disliked the 16" front wheel on the Lotus because it makes the front tire looks like a balloon. And if you correct that with a shorter tire you end up with terrible tire/fender gap. And if you correct that with lowering you'll bottom the front out on just about anything. Fortunately for me I don't track my car, so the simplest solution was to take up that space with wheel instead of tire. I have experimented with 16/17 and all manner of tires, and 17/18 as well, just to see, and the 17/17 definitely works best to my eye.
Third, I prefer high quality, lightweight wheels. I don't always choose those things because I'm a photographer and like to give my car different looks for different seasons/backgrounds (I have 4 sets at present), but I'm so easy on tires and wheels I can run anything and get away with it. But out of all the wheels I've ever had, the Monolite takes the prize for quality and lightness for sure, absolutely stunning.
Lastly, the super light 17 x 8 +31 and particular design of the wheel is PERFECT for the front of the Lotus IMO. You can literally run a 195/205/215 or even a 225 and get away with it. Beyond that, it'll fit any brakes in the world without a spacer. It's just a bonus that you don't have to feel bad about the weight because they are so damn light.
And yes, I want 17 x 9 +32 for the rear because that's flawless fitment for aesthetics, making a 235/245 and 255 easily possible. I spoke with Shinoo about it and it's impossible at any price, but he said that 17 x 8.5 would be possible if enough people wanted it.
So, if it had it my way, sets of the below sizes would be available...
Front: 17 x 8 +31
Rear: 17 x 8.5 +31
Knowing me, I'd probably buy 4 of the 17 x 8.5 and run a 215/40 and 245/40
