Going back and forth isn't really bad. It's weird for me to go to a thin 4-string neck from a 5 string though. Also, the Fender is not capable of the kind of action that the Dingwalls have. It can be respectably medium-low but that's about it. It also has big frets...I've come to really love the REALLY thin/low fretwire on the Dingwalls, which have 'banjo' frets on all the modern ones.
I use the Steinberger Spirit for any gigs that might take flying or really tight on space...that one is a mind-bender without the rear-swivel plate on it. The whole bass rides about 3 frets further to the left making a long reach strange right hand placement...and it's super easy to just be a few frets off on it if you're not careful.
