How many and what type of arrow / bolt are you stocking?

[NorthernRaider]

My very limited research so far leans towards Carbon arrows if I was rich like SD & Nemesis, My crossbow experience and old archery practise leans me towards alloy like SD says, but my budget it making me look at the glassfibre composite arrows but replace their useless soft alloy target tips with steel or brass slip on field tips. Thats providing I can find suitable tips to fit these Armex/ SMK/ Generic arrow shafts ( I dont have a micrometer so I'm not sure of their actual diameter, but with a rule they appear to be 1/4 inch or 6.5 mm wide, anyone got an arrow and 0-1inch mike they can put to use? )
