I was able to try out the Slik Sprint Mini GM this weekend using the 15x binos on top. They are sturdy enough, detected no vibration, but still lightweight (1.6 pounds) and compact. Leg angle is adjustable. Was using a Velbon PH 157-Q head.
The Outdoorsman also makes a sturdier lightweight tripod, but also spendier.
Prior to the Slik, I used a Velbon Chaser EFL-4 tripod, sturdy, adjustable, but a little heavy (3.2 pounds).
