From mini spikes to mini pins

[gnr racer]

Have been using mini spikes on my B44 since my return to 1/10th indoor (2 months) on carpet/polished surfaced but going through a set of Schumacher yellow compound mini spikes every 2 club days,so an expensive time!
Tried mini pins because aparantly longer longevity but i really cant get on with them,car feels way too edgy..am i missing something? maybe trim the outer pins?..or do i need to change my driving style
