PLH and Dome Guide
We measure Parting Line Height (PLH) and Dome on every disc so you know what you are actually getting, not just what the flight numbers say.
Parting Line Height (PLH)
The parting line is the seam around the middle of the rim.
- Higher number = higher PLH = more overstable
- Lower number = lower PLH = more understable
This is one of the most reliable ways to compare stability between discs of the same mold.
Dome
Dome is the height of the flight plate.
- Higher number = more dome
- Lower number = flatter top
Flatter discs usually feel faster and handle wind better.
More dome typically adds glide and carry.
Why we show a range
You will see:
- The measurement for the selected disc
- The full range for that run
The range gives the number context.
Example:
PLH 6 (range 4–6)
That means you are looking at the most overstable version from that batch.
This makes it easier to:
- Find true backups
- Compare multiple copies
- Dial in your stability exactly
Flight numbers describe the mold.
PLH and dome describe the individual disc.
Tritanium eXtend Low Compression Arm Sleeves are scientifically designed arm sleeves to provide graduated real medical compression Level1 (10-15mmHg) support to arms without motion restrictions.
Tritanium High Compression arm sleeves are the same sleeves worn by Simon Lizotte. We've brought the High Compression arm sleeves, and other Tritanium products like this one, in from Finland. We're the only place you can get them in the United States.
eXtend Arm Sleeves provide significantly faster muscle recovery after hard workout. They also minimize swelling and reduce exercise-induced muscle soreness, pains and fatigue, and enhance rehalibition from injuries.
eXtend Arm Sleeves are lightweight, easy and comfortable to wear and can be worn long periods of time, including overnight use.
Note: The package contains one (1) Arm Sleeve. The XS and S sleeves are white. The M, L, XL, and XXL are black.
The four numbers on a disc tell you the discs’s flight characteristics: speed, glide, turn, and fade.
Lower speed ratings typically translate to a disc being easier to throw, but may not go as far. Higher the speed, further they’ll fly, but they are more difficult to throw.
Glide tells you how much it wants to stay in the air.
Turn indicates how much it wants to turn to the right at high speeds. -4 will turn more than -1.
Fade tells you about the end of the flight. The higher the number, the stronger it will finish to the left.
