When I experimented with short pips on my backhand, I tried both Spinfire and 802-40. Spinfire is indeed much faster than 802-40. Plus Spinfire comes in various interesting colors (I still have one sheet of purple and one sheet of pink Spinfire on two of my spare blades)!
Spinfire plays very much like inverted. It is a good short pips if you want to generate some spins yourself and not be passively blocking all the time. It is a very good rubber. The spin was good for my backhand serve and I could loop with it to deceive my opponents (well because I could generate some top spin but not that much top spin since it is short pips after all). Yes the trade off is, it is more spin sensitive so you cannot be lazy in your blocking and use the same angle all the time. When the opponent's top spin is very heavy, you do have to close your racket angle quite a bit.
Friendship 802-40 is slower. But still very good. Yes for 1/4 of the price, you might want to try 802-40 first and see if you like it. Then later on, maybe upgrade to Spinfire for the speed. Don't forget: He Zhi Wen started playing in the 38mm celluloid ball era so 802-40 might not have as much speed necessary in the 40+mm plastic ball era we are in right now.
Both 802-40 and Spinfire do not have much wobbling effect which is what I like about them. I have heard from another player at the club that Moristo has more wobbling effect if that's what you are looking for.
When I changed my backhand from inverted to short pips, my goal was to become more active in my backhand play (meaning more hitting, more looping, more active blocking, etc.) so having something wobbly was never in my book. So I tried Spinfire and 802-40 and that was it. I did not try any other wobbly short pips. Since that short period of experimentation, I am now back to double inverted. It was fun to play with short pips and I would still take it out to annoy some of my clubmates once in a while. lol
My personal opinion is, if you are looking for wobbly effects, then might as well go the long pips route. I have tried short pips, medium pips and long pips. I found medium pips to be the worst of them all because it is like a half-a** rubber: good at nothing and excel at nothing. So either go for short pips for the speed and placement (and if placement is important for you, then you do NOT want the wobbly effect) or go for long pips for the wobbly effect. Skip medium pips for all intents and purposes. Heck I would even recommend anti if you want something stable, over medium pips.
