Tradtech Pinnacle II & traditional risers balance

I have just got a new riser: a Tradtech Pinnacle II.
I usually shoot Olympic style bows and risers and I have noticed that this Pinnacle riser was behaving very differently.
Usually when I shoot I am used to have my bow staying still in my hand or falling forward (even with no stab), with this riser the the bow falls clearly backward toward me.

Is this a particularity of the Pinnacle II riser model ? Or is this the normal way traditional bow risers work ?

Thanks...

It's because the Pinnacle's geometry is just scaled-down Oly style. Basically the center of the riser is fairly high in the grip (I've measured one). There are some risers that place the center very low in the grip and they tend to balance better, but they also aren't $300.

There are non-permanent ways of adding weight to the Pinnacle but they require some metal working.

They are all just scaled Oly geometry, some with more or less reflex. The metal ones balance a little better because they have an internal weight.

Only one or two bowyers are making risers which are really designed to sit upright without weights.

I wouldn't call the TR-7 a barebow riser, it's just an Oly riser that can have some weight added. Even most Italian BB risers need their internal weights. Even the 650 club which has both a massive bottom half and less deflex just barely sits upright once you get the tiller just right.

Nobody in the US makes an ILF riser which will balance completely bare with the possible exception of one of Bob Morrison's wood/phenolic risers, but I haven't shot one personally. They are also pretty huge money.

Border in Scotland makes some that fit the bill:

Not cheap though.
