Replying to Skins

im looking for some skins to use on my volkl gotamas (137-106-122). from what i can tell the only two companies worth buying are black diamond and g3, both priced similarly at about $140 and both have lots of sizes to choose from. i also saw that you can buy army surplus ones for $20, but the only size they have is "about 2.5 inches across" which might be two narrow? it would be cool to only spend 20 bucks on skins, but i wouldnt be surprised if they barely stick or just suck in general. what are your thoughts on these three options?
