RAP4 and TechT cyclone upgrades are pretty much the same, they both are made with aircraft aluminum alloy so They both will give you awesome performance. I have the RAP4 upgrades and they are awesome, the only thing I didn't like was the paddles. It says "soft" but it's barley soft to me.
The soft paddles are used for less ball breakage, but I got to say I haven't had a ball break even without the paddle. I got to say, I like the TechT designs and looks but when it comes down to price and performance they both do the same, but RAP4 is much cheaper. You can get it all for only 50 bucks.
