I am comfortable diving my rEvo with on board diluent (3L) bailout via a BOV to around 10m.

A bailout is only required if something goes wrong with the rebreather.
The size of the bailouts (multiple are often needed when deco is involved) is based on the profile of the dive.
Doesn't matter if the bailout is onboard or not, just that you have it and enough of it.
On a shallow, no deco, no overhead, just get in the water dive I will typically just bring an AL40 of air. That slings just like the AL40 of deco mix on the bigger dives. So same basic gear configuration. And I keep adding bottles to keep up with bail out needs as the dives get bigger.
The issue of using the DIL for bailout is if the reason for the bailout is something wrong with the DIL. And there is so little of it to start with. 23 cubic feet is the start of the day, but on the bottom on the second dive of the day it can be half of that.

For me, it just depends on the situation. Backmount is definitely easier for boat dives or similar. In a cave, it depends on how open the cave will be. Something wide open I'd probably choose the backmount LP50s typically right now, but sidemount if I would be doing something with smaller passages.
To the original question, I always dive with off board bailout.
I dive the Poseidon Se7en and am also curious why you are choosing the sport? I would suggest going with the Se7en + Rec. It comes with the M28 and SS sensors. Then when you decide to go deeper with it, you can get the cylinder inversion kit and MAVs.
I have used both the paddle and the M28 and I personally do not like the paddle. It works but tends to like colder water and can be difficult to read in warmer conditions. You will also need the pre-dive list of test codes with you so you know what it is telling you or asking of you. The M28 does a better job of telling you what it is doing and what it wants you to do. Sure, you will learn what the paddle is asking over time but I also find the wet switches to be finicky.

the main reason I choose the sport is simply because of the price
. The type of diving I do as a diver who will use the rebreather only for recreational depth, I don't find the REC to be too useful. Sport has everything that I need. I think If I ever want to go deeper, i can switch to M28 and upgrade in the futurethe main reason I choose the sport is simply because of the price
Fixed it for you.
