it's VERY close msman825! i like 'em so much i got ahold of CC and was able to include samples in this years ZoaID.com calendar!

(those who get a calendar this year will get 3 plugs to play w/)
i'm not affiliated w/ them at all, nor sell it - i just really like the product.
BAF used to be my favorite -- but these *almost* lock into place. i'm not knocking BAF - still use those too. and i've got no beef w/ the ceramics either - good product too! just preference is all, ya know?
the trick is to find tapered eggcrate. out here, Lowes sells non-tapered, and home depot sells tapered. my local supplier of black eggcrate (precision plastics) sells tapered black eggcrate as well.
but i've been told that in tucson az, it's just the opposite w/ home depot and lowes... so if you follow suit, bring some plugs w/ ya to test w/ in the store, heh!
if you put the 'fat' side up on the eggcrate, these plugs *almost* snap into place!
basically, i can place one in, and lift up both the plug, a 12 x 12 piece of eggcrate, and 5 frags on the eggcrate and the frag plug will not pop off.
but -- that's only w/ the tapered eggcrate.
i have noticed that the eggcrate doesn't appear to go through the strictest QC, heh! sometimes they are tighter than others. i'm wondering if i took a heat gun to the plugs and bent in the legs a bit if they'd be even more secure -- or at least on the 'loose' eggcrate. i picture heating up 10 at a time, a quick squeeze, done? but i've not tried it yet...
