Flame sterilization or alcohol?

Which do you prefer? About to start my second batch - first time I tried flame but didn't have an alcohol lamp, which I do now. Is it easier just to wipe the tip of the needle with alcohol?

alcohol will not sterilize inside of the needle.
it you are sterile from the get go, you won't need to flame.
if you suspect anything inside the needle, flame.

Umm as far as I know:
Flame - heats the inside of the needle so you get rid of the contams there.
Alchohol - airborne crap that couldve landed on the needle.
I thought it was best to do both and WAIT till the needle has cooled down and then wipe it with an alchohol swab to ensure it isn't contamed.
but i'd wait till the growing gurus answer

or buy a case of sealed presterilized needles so they come to a couple pennies a piece, use once and throw away, skip all that other noise

I suggest flaming the needle red hot, then using the first couple of drops from the syringe to cool it down. That way, you know the inside and outside of the needle are sterile. In other words, heat it red hot, then allow to cool for only a few seconds and use. RR

I loaded about 12 3cc pre-sterilized brand new syringes with LC last night. I happenend to have a huge plastic tub of them though from my other projects.. Syringes are cheap as hell on the web..

wow 3cc talk about a tedious pain in the ass. i use a 60cc for LC and 20cc for spores. 
but yeah i dont wanna do no linking to non-sponsor sites but if you look around you can find syringes and needles dirt cheap... places that ship anywhere, quickly, no questions asked... unlike all the paranoia people have about going and buying them from somewhere in person... i got 100 needles for like 7 bucks. its not even worth trying to clean them or re-use them. i still keep it wrapped up in an alcohol soaked paper towel between innoculations so its not exposed to the air, but definitely dont bother flaming... they're sterile out of the package, then i apply the garbage can tek! even more peace of mind from a contam point of view, even less work from a lazy man's point of view.

i put 2-3 in a half pint brf cake... 5-7 in a quart of wbs. love sticking it in the middle of a wbs jar, spinning the jar around as i squirt away, checking back 48 hours later and seeing almost the whole surface against the glass already done all the way around. 
i just hate making spore syringes, so when i do it, i do it up. i also dont like to have to open my LCs for long nor stick things into them repeatedly, so when i dip in for some i dip in for a lot. i hated working with 10cc syringes... id go insane with 3cc ones 
and why on earth would you make your jars on the moist side. it only slows them down and encourages bacteria. there's plenty of time to add moisture after colonization!

probably not.. Iono im still getting used to the way WBS looks after pc'ing. But i guess im doing it right because i have fully colonized and spawned 15 jars already i have 3 LC's going and i just innocced 12 more jars last night as well as two bigass myco bags i made up with WBS, some BRF and some coffee just for fun..

I allways flame the needle first, than wipe it with alcohol (that cools it off too), wait a little and then inoculate... works great

I do BOTH
First 70% isopryl rubbing alcohol, generously
THEN
With bics lighter, zippo (doesnt matter) I flame 3/4 of the needle, especially the tip until it turns red, then inoculate as soon as possible
month of July did almost 200 innoculations with only 2 contams
thank god,allah, buddah for FHs

Thats a pretty good ratio. Just make sure your needle isn't so hot that the spore solution isn't boiling then it passes through the lumen of the needle. Otherwise the spores wouldn't be too viable.
Also, noobs, please be careful when working with alcohol and flame. Use common sense.
