I did about half of my time building in my own plane and have had no problem getting offers. I did a lot of actual traveling though. A trip from san diego to Cape cod via key west, then back through Chicago. A couple of trips to oshkosh from the west coast as well as almost 50 hours of formation flying. I feel like the time in my plane helped more than hurt because i didn't just stay local and burn holes in the same sky.
I got a CJO on Jan 28 and go to CTP June 10, start ground June 21 in the ERJ. I was told that since i have my hours they could put me on the wait list and probably get called to go sooner but i chose to keep that date to allow me to settle some things at home and to prepare.
