A few gear questions. goggles/sling

[snafu]

Well this is a few small items I need to get before BE4 and I am looking to MIA for some suggestions or advice.

I use flakjack goggles like quite a few others I have seen around here. My goggles don't fog too bad but I get a really bad fishbowl effect were water just builds up on the lenses.

My first option was to buy a goggle fan, something like this kit seems like an easy option.

This dual kit from ebay seems like a good deal although the fans look a little big for goggles.

I also came across this pair of ACM turbofan knockoffs. Although I would rather not buy crap from HK.

Last but not least I really think I need a sling as I don't have one at the moment for my cqbr and it sucks to go all day without one. Single point only is not an option as I use a chest rig not a vest. Plus I like the option of slinging your rifle under your arm or on your back when needed.

This sling looks very versatile.

Any input would be much appreciated guys.

Why do you think you can't use a single point with a vest? Anyway, I don't like that IAS. I love convertible slings, but the use of MASH hooks for the front would make it slower than I like to convert, and the fact that you can't use it with both points slung makes it pretty weak compared to the MS2. The IAS might be cheaper if you already have the QD sling mounts, but if you'd need to buy them to complete the kit, the price ends up almost the same.

Personally I made my existing Vickers 2-pt slings into convertibles with some webbing, O-rings, and snap shackles, because I like snap shackles a lot and nobody seems to make a sling with them in front. With the convertible concept in place, I reverse the normal Vickers setup. I normally have it worn long, where it works for strong-side shooting in 2pt mode or total freedom of motion in 1pt mode. If I grab the adjustment tab and close it up in 2pt mode, it pulls the gun in very close, which I like for long walks to and from the parking lot or dead zone.
