Here's what I would do:
1. Get the heaviest BP Fred has.
2. Buy the webbing/hardware package from him -- that's a good price if it includes the webbing, SS hardware, buckle, etc.
3. I like the Halcyon crotch strap, but I wouldn't spend $30+ for it. If I couldn't make it (you can if you have a grommet tool), then I would make my own as shown below.
4. Get a 55lb (maybe 45lb depending on which tanks you are going to double up) Halcyon wing from the cheapest supplier I could find -- shown below. You'll want to double up that LP95 someday (even if you don't know it yet
), so I would get the 55lb wing and use it for everything -- unless I could afford to buy a 27lb wing as well for singles. If you're on a budget, get the 55lb wing and just use it for everything now and get the 27lb wing down the road.
5. If you're diving singles, get the heaviest STA Fred sells.
6. I would/do use a V-weight for doubles so I don't need a weight belt. For singles (LP95), I use a weight belt. If money isn't an object, you can double up on BP's and STA's I believe.
