I mayself am new to the whole thing, and have just bought my first bike. I know how you feel wanting to make sure that you get the right ride.
I rode quite a few different models trying to find the one that i was most comfortable on. From my Father-in-laws Vulcan, a friends Iron 883, A goldwing, and a few others. MAke and model didn't matter to me, i wanted to be comfortable riding the thing (i was scared of dumping) I ended up with the Softail. It was the one i loved from the first sit, and now i own it.
Try everything you can, and get the one that feels "right", both in ride and for what you want.
My wife loved the Wide Glide, so we may be buying another bike later this season, or next year.
There are far more experienced people in this thread giving better advice than myself, i just wanted to let you know that someone else has been through the same thing as you.
