Rather than drag Aimee's hybrid thread off topic, I'll start a new catch-all thread for anyone wanting to talk about some used piece of gear they've picked up.
I just took delivery of a used Callaway Diablo Octane 4W that I won on an eBay auction. I had been looking for something like this since Aimee picked up her 4W a year or so ago. I've never hit one of these so I was taking a flyer, but I figured that I get along so well with the matching driver, I shouldn't have too much trouble with the fairway. Not much risk considering I only paid $35.
I took it out and hit a few balls into the sod field beside our house. Everyone went dead straight! Easy to get up too even from my ample "rough". I'm not sure of the distance, but I hit a few 3 hybrids for comparison and they were 10 yds.+ shorter. I'm going to like this thing!
It's nice when you can pick up a new (to you) club that slots seamlessly into the bag. I had the same good fortune earlier this year when I added a matching 5 hybrid to my 3h and 4h that I already had. If the 4W works as well as I think it will, it won't be long before I'm raiding eBay again, perhaps to add a 56° and 60° wedges to replace the 58° that I'm currently using.
