I’m still new to all this but a lot of the window mounts seem the same to me, and I’m not really impressed by them. I’ve only seen photos online but Vanguard came out with two recently (one pan and one ball) that look to be pretty good quality/value. I think I’m going to give the ballhead a try this season. I believe they’re called the VEO’s?
Only other experience I have is with a Swarovski/Outdoorsmen ballhead Frankenstein combo that was finicky but worked well enough once you got it figured out.
