I think quite a few have Saddlemen Slant Drifter Jumbos. After W&M compact slants (look good on a Speedie but waaaay too small for an America), it seemed you just couldn't get big enough, and big looks good on an America... to a point. Just got the latest Dennis Kirk and saw that Saddlemen has not only regular and jumbo, but now have Extra Jumbo, and Extra Extra Jumbo!
There's a fellow at work who rides a little Suzuki cruiser with the regulars and it looks a little too small even on his. The jumbos look just right, although I'd like to see the Extra Jumbos up close. Those Extra Extras look really big in the catalog... I think maybe too big!
