This is almost gonna be a how long is a piece of string question!
Only issue with this is you will have alot or biased comments mainly down to sponsored players.
Each marker has their own highs and lows which may effect other players whilst other might brush it off.
A high performance marker should be
fast
Accurate
Reliable
Good looking would be nice due to the ammount you will pay for it
Ive owned a fair few markers and the one ive really fell for are the AKA markers- ugly as fcuk but uber fast and dont break. which is exactly what i want in a tourney marker. Ive over looked the point that the are fairly heavy but they are a strurdy marker to go with it.
To cut it short - i like vikings - and for closed bolt i like Excalaburs
Others I like for same reasons are Xmags - man u ever seen one fly!!
