Toothbar or toothbucket? First question; do you have Quick Attach on your FEL? If not go with the toothbar, two bolts, 3-5 minutes to convert your bucket either way. Otherwise I would think it would be a huge PITA to go switch between buckets. Love my toothbar, it stays on my bucket 99% of the time. Will probably stay on until the snow flies and lands in my driveway. If money/space no object than a dedicated toothbucket to beat the crap outta is not bad either.
Either way put some aggressive teeth on the Kioti, really improves it's bite!
