I've worn the Sly's and Dye's in the shop down my street and liked/ disliked a lot about them. I shot a few games w/ my bud's I4's and they were just a bit skinny, wore the Sly's around the shop while trying to listen about other products but couldn't really hear much since everything was muffled. BUT THEN I tried out the Grill and loved them, I've been playing with them ever since. My only real complaint is that since the company is under new management they seem to have halted research into a better lens..
Being the broken record here and agreeing with everyone else I'm going to say it's all really up to style and personal comfort. At this range I'd definitely try before you buy since you'll be dropping a pretty penny for a nice pair of goggles that will last you hopefully a long time.
I4's > Profits IMO.
