I was talking at length at MACNA with a retailer as I was deciding which to get for my 75g. The 26s are cool, but I don't totally see how you can get the same coverage, I feel like some shadowing is likely... They claim they get the same coverage cause of the optics, but I feel like physics makes that impossible and there must be additional shadowing. However, you probably get better color blending with the 26s. You can tell which part of the tank are under the blues and which are under the green/red pucks with my Hydras. Doesn't really bother me tho, I still think they look incredible. The guy at MACNA made a good point and said if your lights are out in the open then the 26s might give you a cleaner look.
I was at MACNA too. I talked with AI. I agree with you about the shadowing. It's about the number of fixtures and the amount of overlap. On your 75, two would work and is enough light but with shadowing. Three would be better. I have two over my 4 foot tank and have been thinking about adding more Hydras or adding T5s to help with the shadowing.
