I upgraded all the pegs on our pair of Oztents, and they work brilliantly. The mix of long pegs for soft ground and short pegs for rocky work well, and setup/pulldown is a breeze with the provided torx bits.
Our recent trip to the mid west of WA dealt with a few days of 50km/hr winds (gusts at 65) with not a problem.
The Oztent guy rope plastic end catches fit under the peg "hook" without having to uninstall the peg, which is great for modifications/adjustments after setup, for example pegging out the rear window flaps on the nice days/warm nights! Video showing this below.
