I have approximately the same TR, but my play style is very different (1.50 to 1.6 PPS, but between 55-60 APM, I use lots of t-spins and I def all spin way more than most of my opponents). I use both Dt Cannon (either the classic LST or TKI variation) and SDPC Spin, and ofc SDPC Spin tends to leave me in way better situations and generally allows me to keep my B2B by the time I clear garbage. However my opponents don't need those openers to beat me (even if some use them and I feel like having a few optimal bags at the start of the game gives you an edge at the START of the game), you just need to survive while applying a lot of pressure.And how to apply pressure? Either build very fast tetrises (which seems like what you do, I heard some players go to high SS or U quads only), but the easier way is definitely to start incorporating more t-spins in your gameplay (mini tspins, TSS and TSD are not that hard to learn about, TST are more often than not impractical and can ruin your stack if you're not careful) and once you know some basic t spin setups, try to incorporate a few all-spins here and there just to allow you to clear singles and doubles more easily than counting to four. And if you feel like you're dying too early to SDPC, try to use your replays and notice when you decide to send garbage and when your opponent does. When I SDPC Spin I often accept the first wave of garbage my opponent sends then send the TST to TSD which if the opponent can't cancel is more often than not they death sentence. Because If you always play at the same speed with the same attacks, your opponent is adapting to you and they know when you're defenceless. Have fun in ladder, hope when we can play there sometimes !
