Sounds like the OP is more of a TOM kind of guy, not that there's anything wrong with that. LOL

It doesn't need upgraded flipper coils unless you want to break the plastic over the center standups
all the time.

It's a challenging game ala IM. Maybe not everyone's cup of tea.
Another game that kicks my butt before I get anywhere
close to wizard mode 99% of the time is JD. Except BSD doesn't have a wizard mode.
In my 8 game collection (plus TOM on loan) I like BSD's unique ruleset and style of play. I tire of long playing games and when you play to win the only way to shorter games is to throw them. Not with BSD.

I use white rubber and bouncy flipper rubber (not black). It takes time to learn how to catch the ball because that little bit of extra flipper seems to make all the difference when countering ball spin.

When there is no load on the flipper, the tip of the longer one travels at a higher speed as it follows a longer circumference. The ratio of flipper coil strength to ball weight is such that a 1/8" flipper length difference probably has minimal effect on ball launch speed from the flipper tip.

Blue, yellow and red label WMS coils each have different numbers of windings. Less windings is more powerful.
IFrom what I have read the ranking from strongest to weakest is: FL-11629, FL-15411, and FL-11630.
