I don't read cards so much by images on the cards. Actually, I do use the images on the cards but it's not necessary for me to see every minute little detail. The only deck I've ever really felt was lacking in that respect is the Shadowscapes but it's one of my very favorite decks and I do read with it. The names on the cards are very hard to see, though, and that's my main observation of difficulty seeing things on the cards.
Each reader reads in a different way, so if you're a reader who has to see minute details, then you're going to need big cards. I presume that means you're going to adapt yourself to that need by putting a desire to handle and shuffle the cards like a smaller deck out of your mind and you'll get used to handling the bigger sized cards.
I find myself being a little frustrated by the really small number of cards in a Lenormand deck when it comes to trying to shuffle. I like the Gilded Reverie because the cards are bigger. The deck is thicker because the cards stock is very thick, so they're hard to shuffle but I use a fan with those and the Oracle of Visions. Those are oracles, though, so I think maybe that also helps me to not need to shuffle them a lot. Oracles are used differently so my shuffling obsession isn't awakened so much by them. Tarot, though, is another thing----I do feel I need to riffle those to get into the "zone".
