Decided to give the Vivitar 285's with the PW's one more chance instead of just using my Canon 580EX's but this time in a different gym with different lighting from the one I shot at last week (https://www.fredmiranda.com/forum/topic/843255). Better lights in this gym. Shot 3 games using the Sanyo Eneloops and didn't have to replace them.
Used my MK2N with the 70-200/2.8, ISO 640, F3.2 or 3.5, manual mode @250, center point focus, flash on 1/2 power. Flashes were set on the corners about 6 feet behind the baseline and on 13 foot stands.
The recycle times are about less than a second to a second depending on the batteries. Less, when they are freshly charged and I can get thru 2 games. Around the 3rd game, the recycle time is about a second, so you have to choose your shots.
I also use Sanyo Eneloops for my batteries which are a lot better than the other rechargeables.
