I've done a few, but still haven't perfected the technique (though I'm getting closer). I'm happy to give it a try, if you're willing to take the risk (should be relatively low, but there's always a chance of a problem) and are willing to be patient (I have to cast outside, which requires nice weather). For me, the worst part is gluing the skins to the tubes - I'm really picky about how I want mine to fit. If you can send some pre-glued tubes, I can turn the casting around faster.
Anthony, don't feel TOO bad, apparently Aries aren't much better about such committments - I owe a fellow member a set of blanks from a trade several weeks ago! (thanks for your patience!)
