So far this season we have used:

- 4" VersaWheels on all (8) of our drive wheels, for both our practice and competition bots. They seem to be holding up really well, with minimal wear so far. Subjectively they provide good traction, outside of driving on the tape while trying to push up the pyramid pole (wheels are spinning in high gear).

- 2-Stage Ball shifters. The biggest benefit for us so far has been the lack of weight, allowing us to put it into other systems. Can't comment on the shifting, since we don't have pneumatics and haven't quite figured out how to shift them with a servo or motor yet (it's a work in progress). We dialed high speed to be very similar to our previous AndyMark supershifter setup (~14 FPS). I think low gear turns out to be a little faster, so that should be nice once we get them working.

Only concern we had with these was how the encoder gear was a press fit, instead of a more secure connection. We picked the two gearboxes that had the best press or had no apparent slip between the output shaft and the encoder gear and put those on our competition bot. We haven't had use for the encoders so far, but this may be an issue if we want to try and back up after we shoot our auto shots.

- VersaPlanetaries (100:1 and 300:1). We are using the 100:1 to power the feeder that pulls discs into the shooter, with an AndyMark 9015 motor. We also have (2) 300:1 planetaries w/Banebot 550s coupled to a 3:1 chain reduction to change the angle on our shooter. So far (knock on wood...), they have been great at moving the shooter angle and lifting the robot while hanging for 10pts. These little gearboxes are probably the best product offered in the entire lineup. The ability to mix and match ratios and adding stages to get the right setup is priceless. Not to mention the flexibility to work with every motor allowed is awesome.

Some improvements could probably be made to aid in assembly of the motor to the plate (as discussed elsewhere), but if care is taken you can everything lined up and running smoothly.

- Single stage, double reduction gearbox. We are running this on our climber with (2) CIMs and a ~4:1 chain reduction, to pull the robot up the tower. No problems so far...

As well as running all 888 Victors for every speed controller, and other misc harware (chain, bearings, sprockets, etc..) .

We have did not find a use for the Bag or MiniCIM motors on this years robot.

We're pretty much all in on the VEXpro lineup this season. We have seen no reason not to be 100% satisfied with the price, quality, and performance of any of the products.
