I'm 6'2" and 240 lbs, have a Volusia and love it. Have ridden many bikes and IMHO the Volusia will give you 95% of the performance of an LC 1500 for about 60% of the price.
It is built big, magazines all highly recommend it. Motorcycle cruiser for one states that it's like getting an 1100 for the price of an 800.
Have you sat on a V-Star ? at your height you'll have your knees sticking up above the tank. The Vol is roomier than either the V-Star or the Shadow. If you need space for your bod you'll have to go up to 1500cc's or more to get better room than the Vol.
Differences in performance are negligeable between the Vol and the 1,100's and even the 1500's won't beat you by a wide margin.
If you're looking for a nice reasonably priced bike to cruise on then the Vol is definitly an excellent choice.
