the milling just makes it look cool.......... drops the weight by a few grammes, but other than that it's cosmetic.
If I was that bothered by the weight I'd use my E-blade more than my timmy, but I don't. Probably would matter if I was playing front and about three feet tall though.
Anyway, I don't go in for the whole my marker is better than yours thing........ it's all down to taste. Those who shout loudest are usualy trying to convince themselves that they've comitted to the right marker. I've fired most and I've bought loads..... got a couple of E-blades, timmy, eclipse cocker and an eclipse shocker I still love....... Race on order, never fancied an Angel and no one will convince me otherwise....... just not to my taste and I can't pinpoint why. I'd never try to convince someone else to use a cocker or timmy...... you need to decide for yourself. For instance......... if lightweight and small size is important to you, then a shocker 03 will be your thing, if having a marker that can make paint come out of it is important then anything but a shocker 03 is your thing
