hehehe...the longest joint that I've smoked, was about 10"
I rolled it myself, and did it free-hand (ie, no mats or tables lol)
I was so proud of it, that I gave it a name - I called it "The Wookie" lmfaooo

It smoked like a dream, too - drew lovely, tasted awesome (used about 50/50 baccy to weed ratio), and killed us all (threre was 3 of us)
I also used Rips, and could only just about hold on to it when I was doing the roll.

Ahhh..."The Wookie"......
