Stabiliser question

[geoffretired]

I see lots of stabilisers set up with long rod, V-bar+ short rods and an extender.
What would the differences be between the two systems below?
a) 36" long rod with v-bar+ short rods.
b) 30" long rod on 6" extender. V-bar between the extender and long rod.
Short rods are longer than the first system to place the end weights in the same position relative to the riser.
I'm imagining the total weight to be the same in both and I think the centre of gravity of the two systmes would be very much the same ,if not exactly.
Is this just two ways to get the same effect or is there some real benefit in having one rather than the other?

Assuming variable length twins as well as angle - it would feel more front heavy on the one with the v-bar between extender and longrod due to the fact that the V-bar (presumably non-zero mass) will be in front of the bow by 6" as opposed to 0".

You are right there,Shirt, never thought of that.Thanks.
I'm not trying to be awkward here, I'm just curious. What if the overall weight and balance, by some coincidence were the same? Is there something better about reaching that situation with an extender?

[disbloke]

As far as I am aware the purpose of the extender system is to allow you to keep the same, relative, centre of balance on the riser rather than moving that position behind the hand, as would be the case with the v-bar against the bow.

As for the angle on the v-bar it would seem a lot of the top archers are using a straight bar, besides that the v-bar is being used as a counter to torque in the riser. By the nature of mechanics means that the most efficient way to achieve this is by keeping the v-bar on a level plane with the upright of the riser rather than behind it.

There's bound to be someone here who will correct me if I'm wrong, that's just the way I see it.

Thanks, disbloke. I see what you are saying about the balance behind the hand or more up front, using an extender.
I'm probably not saying things very clearly, but my question is a bit different from that. What I'm thinking is, I can get the balance forward with an extender or I get it in the same place without, by using a longer long rod and shorter back rods. If the bow balances the same and weighs the same which ever system I use, is one way a better system for some reason that I haven't thought of?

I can answer that one Geoff.

Without an extender, my short rods interfere with my stance when nocking an arrow.

But that may be due to the fact that I have a big a**e.

So, it's not a bow balance problem it's a way to get the back rods away from the back side!! Well I'm glad you told me that. I can rest easy now. I just hate mysteries of that sort. Thanks a lot Morphymick. Great!

It's the only reason I got one Geoff.

The static balance of the bow was checked at Lilleshall on my improvers course last month and was spot on. The dynamic balance was video'd and was also spot on.

It works for me.

Thanks again for all the help. Another mystery solved.

so when you shoot all over the target you car'nt blame the bow
