Jesus Christ 20g? Damn bro 22.5's look like a harpoon. 13 g, man you guys are fucking nuts. I always just went with 22.5 because I thought that was standard but I tried 25g once and I'll never go back....well unless I run out of 25g's.
LOL, what a great idea!!I was kidding of course, Last year I couldnt find any and they had some at my school lab that were 15g. I tried and Im not that squeamish I just jabbed it in, but my friend would sit in the bathroom staring at for like 10minutes before doing, he just couldnt get over the size
