If you are going to use Wagtail and BOAB, you will find it doesn't fit if you use two tools(applicator + blade) The blade being wider than the normal trad gear. If you only use the Flipper with the combined applicator then there's only the one tool which will then fit in where you'd normally put the applicator. The only downside is the large plastic disc, but all you need to do is to cut a slot in the BOAB to accomodate it. I will try to post a pic but been having problems.
