Yes, that's it. 'cept it's where the boots WOULD have been

Mebbe, for me 4.5 k in a v-weight works, but my 12's have a 15Litre manifold so have a big gap between them.

btw, I dive with Jetfins (turtles, TBC) and no ankle weights.

mmmmm, Phil's patented fin design (heavy fins) springs to mind
EDIT: forgot to mention earlier, I use 8lb/4kg at the moment

If you are completely happy with your trim as it is, then moving weight up your back is going to have exactly the effect you are predicting . I use 3kg at the moment, in the form of 3X1kg v weight blocks. 2 of these sit as near to the bottom twinbolt as possible, and the third sits below the bolt. This is duct-taped in place at the moment (whoops).

You can fit up to 3 blocks between the bolts if they are the sdtandard 11" apart, sooo.....I would think about 2 X 1kg blocks and a 2KG tailweight if I was in the same position as yourself.

ah, we may have a problem then

1. want to keep the boots
2. 12's but with a tight 187/194 manifold

may well be cambanding 2 2lb weights onto the boots then

DIR guys wont like this but you could try using the Patent-pending Ingy Weight system.

These weights can drop straight into your drysuit pockets and, given the principle of moments, means that you can use less weight to trim out than when used higher up the body. Works well for me and very droppable in the unlikely event of an issue.

Essentially you take some lead shot and put 500gms into a ziplock bag. Put the zip-lock into one of those washing tablet mesh bag and you're away. Use as many as needed or add more shot to the bag.

Dead simple. Deffo not Halcyon approved but we are in negotiation*.

What's a drysuit pocket?

If you use a P weight or V weight when you are used to having the weight lower down on a belt then you will have to extend your legs a little to make up for it (as in the Centre of Gravity drill you mention).
Even if the weighting is better, it will probably feel uncomfortable for a time until you get used to it. Tell yourself that you will do at least ten dives and THEN assess how you feel - rather than say on day one that it feels difficult - it will
Once you learn to move your leg/foot position to accomodate weight distribution changes though you will find that you can pretty much do what you want and hold trim. I'm happy to dive with V chunks, P weights, tail weights or even a weight belt (which have their uses too).
HTH

All of the above is bang on!
I use a p weight with twin 12 300bar and also with single 12 300bar and 300bar pony, at first the twins were always trying to turn my head into a plough! once you get use to adjusting your boyancy with your wing you can counter act the ploughing technique as the air is being kept in the same region as the lead and back plate.
Just do as clare says and dont think its wrong after your first couple of dives, you will learn how to counteract it and then you will wonder what the problem was in the first place
