lol @ abodo. My CoC is in my desk drawer... painful.
First of all, good luck with the wedding, Rub. My year anniversary is coming up in a few months. So far so good.
Secondly, I apply to the philosophy of "you're only as strong as your weakest link". While all top powerlifters and most oly guys train with straps to ensure their prime movers get the most work possible, they have different goals than you or I. They want to get stronger in a couple lifts while we want to be strong overall, healthy, and able to perform athletically. That being the case, I always recommend strapless lifting and letting your grip catching up with your prime movers. Doing extra grip-only workouts some time during the day will help too. Things like farmer walks, CoC squeezing , wrist roller, thick bar barbell/db/kn work, towel dead hangs for time or pull-ups, etc. Just 15 minutes 2-3x/week for a month or so would work wonders and help bust through a plateau.
Homemade clubbells are a great idea too. Scott Sonnon even posted an article in his CST magazine (or discussion forum) a while back on how to create safe homemade ones. If you can't track it down on his site, let me know. It wouldn't surprise me if he removed it from his site since he can't profit from it. I'm sure I have it saved on my harddrive some place. It will take some digging though.
