New diagonal, 1 1/4" or 2" ?

Hiya folks, wanted to get some input here. Im thinking of grabbing a new diagonal for my 8" SCT. I only have 1 1/4 eyepieces currently. My question is, is there any reason i wouldn't buy a 2" diagonal instead of an 1 1/4" one? Seeing as how they come with the adaptor for the smaller eyepieces, i figured the 2" would be the better option, but i feel like i'm missing something here. Any help would be great. Thanks!

Your not missing anything. Go with a two inch diagonal. You can use your 1.25 EPs and when you get a 2" EP for widefield work you'll be set.
