These 22g Foxfire looks sort of similar to the Phase 5. I think they might be good. Nevertheless they probably would be equivalent to 24g in soft tips terminology.
I used to prefer straight shape, but now with Phase5 I consider this bullet or bomb shape being slightly better. I improved in grouping in smaller areas with them.
DartsCorner is a great shop as well as Double Top Darts Shop is. I have good experiences with both of them.
I dont get what the "28" is. What is B? Bull? Then from bull and 20 to 15 is only 21 darts. And average of 4? To be honest, I didn´t understand much the system of points you mentioned earlier in your posts. Could you explain it to me?
