Kind of interesting to put it all down like that. I think I captured them all. Have done quite a bit of buying and trying. Bought all of them from dealers or individuals from here on Findmall or over on the 'Depot. Yes, I learned how to use them all, though there are some, like the V3 that I'd not claim to have mastered. The multiple times are due to various things; such as sold it to buy another and then picked it up again later, or I was trying to make myself like them, or maybe I liked them and kept trying to use them but couldn't for what ever reason, etc.
My current ones are in my signature.
