For some reason there are an abundance of Speedo 4803 packs on eBay right now. I've been thinking for some time about switching over to Speedo, and this is tempting. A couple 202VF heads in a rationed setup and I'd be good to go. The only trouble is the recycle time. In particular, the recycle time for this behemoth is 4 seconds, which is about an eternity to me. But even many of the other packs seem slow compared to what I'm used to. Can anyone here with experience shooting the black lines chime in with some thoughts about the recycle times? Thanks.
