I gotta agree with sebas, the early going using SP is going to be rough, unless all you do is bump through the ball and are not very aggressive on BH unless it is an easy smash stepping forward. What you do is your business, but you ask at TTD and people WILL speak up. You seem to welcome it and that is what posting about stuff like that is all about.
OP... The advantages you have already (nicely) said are true, possibilities are there, also possible to achieve this are thinner sponge (yuck !!) or better hands and getting to the spot on time to use the BH.
So many ways to go.
Many Koreans, if not nearly ALL the amature crowd below Div 1 city who are shakehanders do NOT have a spinny BH topspin. Classic old school coaching teaches that the role of the BH is to keep the shots connected so you can stay alive or ahead of the rally initiative and get chances to use your powerful, quick, not so spinny, very fast FH drive that lands deep to a good spot with very fast pace. Even among the Div 1 city top amature crowd, there are not a boatload of players you would identify as having a great BH topspin.
I say that to remind you that you can have a really great game and very decent level WITHOUT having a very offensive BH and if you continue to grow without making your BH into a weapon of mass destruct, you can still grow in level fine. To do that, your BH just needs to be really consistent, well placed, possibly quick off the bounce, and provide just enough pressure from placement or pace tomake opponent NOT attack and give you the chance to flash your good anticipation & step around footwork to use that Macho FH of yours.
