Distance Driver · Both Overstable
The Innova Boss (13/5/-1/+3) and Kastaplast Guld (13/5/-0.5/+3) are both distance drivers, and they fly very similarly.
Both are speed 13, so neither needs more power than the other to reach its flight. The Guld is the more overstable of the two (stability +2.5 vs +2), so it fights wind and finishes harder to the left, while the Boss flies straighter or turns more. Both land at a similar estimated maximum distance (about 139 m).
Choose the Guld when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the Boss when you want a straighter line, an easier turnover, or more help at a lower arm speed.
