Andrew ,
Plenty of Barbel Rods come with two tips,one often being a quiver top.
Think you will find a 1/ 75 top a better proposition.
Nearly all the major companies do them,most of them excellent.
Lately,in the low flows I have used the quiver tops alot,along with a feeder and crushed pellet and crushed boilies.
It will make no differance to the power you can exert,but is more prone to jamming the rings if weed is around.
They are usually better balanced and lighter with the quiver tops.
Pons.
