Mate, I'm not using anything at the minute. Inspiration, motivation and work are putting paid to that. I like the prism, it's comforting but the metering is't that accurate, or at least I'm not that accurate with the metering. I can't see it being that easy using the speed grip with the WLF so the prism is good for that too.
Cheers for the reply Barry and the pic Matt, now I know what to look out for. I've got the morning off today so I'm definately going to get some use out of it.
