Chop-blocking loops with pips is a chaotic tactic. You can do it with short/medium pips too, by the way, and it's probably better to start with short pips if you are used to inverted rubber.
When playing with pips on my FH, I've been able to beat a few 1500-level players, but it's inconsistent. Some of the players don't understand how the spin works, and it's easy to confuse them with a combination of chop blocks and flat hits. Their confusion means that they play more passively, giving me short slow balls which I can easily smash.
However, many 1500 players understand how to beat pips and they can beat my pips game quite easily. If the opponent plays spinny loops deep on the table, it is quite hard to counterattack or chop-block with pips. If your opponent can do this consistently (which many 1500 players can), then you will have to stop chop-blocking and start chopping like Joo Sae Hyuk.
Also, I have noticed even in the ~2 months since I started playing with pips, that some of the players I beat at the beginning have learned very quickly how to beat my pips game. Pips have very obvious weaknesses, and it takes a very high skill level to compensate for these weaknesses.
All this is to say: pips is fun and worth experimenting with, but I'm skeptical that you will see improvement in your overall skill level unless you stick with it for a long time. There are two main skill benefits to playing with pips, in my opinion:
1. Gaining a better understanding of how pips work, so that you can beat pips players when playing with inverted rubber.
2. Isolating the "drive" motion in your strokes, making your drives more precise and not relying on the "loop" motion to spin/arc the ball. I have noticed substantial improvement in my ability to flat-hit the ball aggressively, even with inverted rubber.
