First I would like to say one thing about the Dits, it's a great marker, even if it was to cost 1k or more(don't tell AM though), and that modding it using a few reversable techniques will help, but they are not necessary in order to show the rest that you're good right out the box.

A quick and simple change in ram spring will allow for quicker cycling time. It doesn't require much, just pick up a #12 from any local A.C.E. hardware store and try it your self. note:
too lite of a spring can lead to unwanted bounce, increasing your debounce will eliviate this.
Technical heads up.
Diadem and the Sentinal share the same body design, and therefore the sear slot should be closed off when applied to the Dits.
With this area closed off, you can keep moisture from getting in the grip and wetting the board. Auto exaust tape made out of tin works great for it.
Adding this tape to close off both open slots in the frame and reciever will also maintain the position of the trigger , making reassembly a more straight forward proposition.
