How good does it feel to see the Lakers take back the championship again. I have been typing the same thing almost the whole season, but seeing it now just looks so much better!

THE 2009 NBA CHAMPIONS

We’re all on Cloud 9 at the moment. I’m celebrating until the next run.

I didn’t put enough information in my last one… I’m travelling to Fiji, and I have never dived but I am learning out there with a qualified PADI instructor… I need a travel insurance policy that will cover 30m depth and is British.. Thank you 🙂

???Above answer??? I don’t get that.

I took a peek at just one of ours that we have links and information to and the adventure sports plan covers to 50M. So, that seems pretty common. I have links and information on our site. Look at the Patriot plan and you’ll see information if you scroll down about the Adventure plan.

Comparison based on Personal Experience would be best.

The advantage of split fins (according to the ad-blurb, anyway) is that they allow a much shorter, more streamlined flutter-kick than non-split fins, which reduces swimming effort, and hence air consumption. They are also supposed to be better for surface swimming, since they produce less ‘splash’ (and hence waste less energy) when breaking the surface

As a full-time instructor I used non-split fins (Mares Avanti Quattros) for almost my entire working life (2000-2005) and have since continued to do so on fun-dives. I have only once used split-fins (Scubapro TwinJet, borrowed from a colleague to try them out) and I didn’t get on with them a-tall, likely because I was thoroughly habituated to my own fins.

I found that particular model too floppy, and almost totally ineffective when doing ‘frog-kick’ (like most instructors I know, I hardly ever use the ‘traditional’ flutter-kick). I had no confidence that they could provide me the power and manouevrability that I might require in an emergency–but perhaps if I had taken a little more time to get used to them, I would have got to like them better.

I would however emphasise that I do not have any experience with other models of split-fin, so my comparison is not only extremely limited, but also highly subjective. Someone who buys split-fins early in their diving career, and uses them habitually will likely have a different take on things.
