you certainly can use a springer off sticks ! Prone needs to be a no-no but you can use ant soft support ( to be fair its a very rare thing to shoot a springer prone though in the field )Personally I would avoid a springer.
If you want to spend ages mastering it- and probably a fair bit of money tuning it- you will eventually be able to shoot it nearly as well as a PCP.
You can't use a springer on sticks or with a bipod, follow up shots are slow and they are all hold sensitive to a certain extent.
Or just skip it and get a PCP which you can shoot in the same way you can a firearm.....
as regards getting used to shooting a springer ...? The better quality / heavier models like the TX , HW are little to no problem
Biggest issue to be fair is a great amount of shooters today have no real time in with them or go very budget to try them . I have shot springers from the late 70s and entered FT events from very soon after from about 82? from that time onwards to the present time the tuners Like the Popes with their venom and the design of the pro-sport and TX
/ TXsr can still to this compete .
Big advantages are 1.Cost 2. very minimum servicing 3. durability 4. reliability 5. lower cost of the whole of the kit ( no charging gear ) .
would i go springer if i was re-entering competitive FT today ? Nope ! but neither would i drop a few grand on quality a PCP and then the scope , charging gear to shoot Rats , ferals etc ? Nope!
Each to their own though
